We like to use a turkey fryer/burner, something like THIS, to boil shrimp, various other things in a large pot (its often called a 'low country boil', and is great!). The burner for this has a 'female' type connector that screws onto a standard 20 pound portable LP gas tank. In past trips, I've just carried a 20 pound LP gas tank in an outside storage bin that we use with this burner. This works OK, but I really don't like carrying a separate gas bottle in a storage bin. Makes me a bit nervous, and uses up storage space I'd rather use for other things. Would prefer to be able to tie into, use the permanent LP gas tank on the Motorhome.The problem is that on our Motorhome, the LP tank is on the driver/street side near the front of the MH. Would prefer to use the burner, fryer on the curb (camping) side.Sooo, my question is this: What would be the best, safest approach to allow using the fryer on the curb side? Should I have a dealer run a permanent high pressure LP gas line from the MH's LP tank on driver side over to the curb side, and plug the burner in there? I'm thinking that'd be pretty expensive to do, and would require running a high pressure gas line near, across the engine and transmission. Does not seem like a good idea? Another approach would be to just install a Y adapter on the LP gas tank, and purchase a very long LP gas extension hose that I'd connect and run over to the fryer on the other side just when using it. Would need to be at least 12' long, preferably more like 20'. Can high pressure LP gas hoses be had in that length? I like this approach better, as I could do it myself for much less $$ I'd think.Any other thoughts? Anyone else use a burner like this, and have a similar predicament? If so, how did you solve it?

Average RV labor cost is $120 per hour.Buy a portable 3-5 gal LP tank (standing or lay down) that will fit in a cargo area. This tank can also be used for lanterns, patio heater, fire pit, and portable bbq at any location around the RV or house.

You can have an LP dealer install a hose connection on the curb side for you then connect a LP hose from there to the regulator to your cooker. Gas piping is confusing to many people so this is best done by an LP dealer.LP hoses can be made at any lenght but off the shelf, is normally the 12 foot size.

You might want to consider a Stay a While or Extend a Stay Tee. They are available with a outlet and hose for an external grill and an outlet and hose that will fit an external cylinder. The later can be handy when you are stopped for a while and don't want to move the motor home to fill up the on-board tank.They have some built in safety devices so are better than just a plumbing Tee.You can get a longer hose for the grill. As I recall the one that comes with it is about six feet long. A friend had one made that was about 20 feet long.I installed mine myself - took maybe ten minutes.

Extend a stay is a good idea. You can have a longer hose made at a hydraulic hose shop.Extend a stay fittings are fairly expensive but it is a simple DIY job you could do yourself.I have a connection on the side of my fiver I use. However I will often just carry an extra bottle of LP along. Having a separate LP bottle eliminates tripping over the hose. The bottle also give me more flexibility as to where to place the burner

..Thanks for the suggestions, and please keep them coming.I will look into the 'extend a stay'. Have heard of those, but haven't checked into such yet.More I'm thinking about it, I think a 12' hose should be enough. Will be nice if all I have to do is get an appropriate connector to mount onto the LP gas tank, and a 12' hose. Would MUCH rather carry a 12' hose with us, instead of an entire separate gas bottle.I may also look into purchasing a smaller, portable gas bottle to use just for this. If I can find one a bit smaller than a 20 lb bottle, that is safe(r) to carry in a storage bin, that might not be a bad idea, either.

Thanks for all the suggestions, responses. All very good info. :)

Well, think I've pretty well decided that I'm going to go with an 11 lb. separate gas bottle. It is just small enough so that it will fit down in the large pot we bring also for this, as I mentioned in the previous post.

However, one thing is bugging me, that I'm wondering about: Is it risky, dangerous, for an LP gas bottle to be stored, transported inside a large, metal pot? My concern is that if the tank 'vents' out some gas, the gas will tend to settle at the bottom of the pot. Wondering if the gas bottle shifting around a little in the pot, and it being metal on metal, if it might generate a spark, and.....kaboom.

Or, am I being overly paranoid? Should I maybe make some kind of sleeve, cover for the LP gas bottle that it will fit in to reduce chance of sparks, before putting it in the pot? I know they make covers, containers for gas bottles, but I've not found any that will fit the smaller 11 lb size; they all are made for the more common 20 lb bottles. A 20 lb bottle is too big for what I want to do here.

I use the Extend a Stay as a back up for when my portable LP tank should happen to go empty. Easier to get a portable tank refilled with a toad when parked than buttoning up everything and taking the RV to town for a refill. (with the exception of paying for On-site LP Refills).

DW decided we needed a propane firepit. That will go through a 20# tank of propane in a couple nights (she like a lot of flame!). So, I got the extend a stay and plumbed some fittings and hose so I can use our propane stove, the firepit, and a gas BBQ. I run the hose underneath the coach and mats to minimize the tripping hazards.

Cameco and a few others make the same (functionality wise) products.

I didn't even know my RV came with one(we're second owners) until I needed it and brought my hose and stuff from the Condo on a trip. A lot of RVs come with them or are add ons that may exist all ready.

Extend-a-stay sure does exist. Follow this link Marshall is one of the biggest suppliers of propane equipment. I have nothing to do with this or any other company. Just a retired RVer correcting misinformation.

I will take a photo this afternoon to show you my end result.

..Aside from the concern Lantley brought up about someone tripping over the long hose you run from the MH for this, another issue I have with tapping into MH's permanent tank, more I think about it:

If you run yourself out of LP gas using your cooker, grill, or whatever, you've now also used up your MH's supply of gas for heat, hot water, stove/oven, etc. Now, you have to break camp and drive that big MH who-knows-where in unfamilar territory to get the tank refilled. Not something I ever want to do. I prefer to fill up the MH tank at my convenience at home, where I know of a place close by that has plenty of room for me to get it in and out of.

With a smaller, separate bottle, you leave the MH's gas supply alone, and if you run the separate bottle out, you can just throw it in the trunk of a car (toad), and easily take it where ever you need to go to get it filled.

I like that much better, more I think about it.

Tapping off the fridge won't work. Most grilles need high pressure propane from before the coaches regulator. Ditto for many Fleetwoods which have a tap, but it is low pressure and basically worthless.

Yep, I knew fridge line is low pressure and wouldnt work, when I saw someone mention that earlier. If you're going to use the MH's tank for something like this, you're going to have to run a separate line from the tank.

No extra bottle for me.

There is no real risk carrying a separate LP bottle if it is stored properly. The valve is well protected and plugs can be screwed into the female connection. I have seen yellow plastic bases and square milk crates used for standing and securing bottles. I have seen RVer's strap them to the wall of the basement.
I do neither, I have a 2 gal lay down tank which is near impossible to tip over. Was my fathers.

Ahhh, like so many other things, this has turned into a decision between two choices, both of which have their own pros and cons. :)

Lantley makes a very good point I hadn't thought about (thank you, Lantley): Using a Y connector and long LP hose connected to MH's LP tank, introduces the risk of somebody tripping over the long hose. That could be really, really bad, given that the other end of that hose will have a very hot burner burning on it, and a large pot of boiling shrimp, corn, potatoes, etc. sitting on that burner!

OTOH, carrying a separate LB bottle has its own set of risks, too. Like you said, Lantley, its a case of pick your poison. :)

More I'm thinking about it, I really like the idea of carrying a separate, smaller LP bottle to power this burner. Reason being, a separate bottle has another nice advantage I hadn't thought about: If I purchase an LP hose adapter like this one, I can then use the LP bottle to power our portable grill, and not have to carry and use those small green propane bottles so much anymore. That would free up even more storage space.

I'm thinking about a 10 lb LP bottle like THIS one. It will sit, fit perfectly down inside the pot we have to bring anyway for this, and will utilize what would otherwise be wasted space inside that pot (I measured yesterday to verify the 10 lb bottle would fit inside). And, will provide another good option to power our other grill instead of using those small green bottles. Yes, carrying a separate LP tank inside a pot sitting in an outside storage bin has its risks, but is it that much more risky than carrying several of the small green propane bottles that I bet most everyone carries? I'm thinking not.

Looks like it might be time to pay the Camping World store a visit. :)
