talk to me about built-in LP gennies...

Greetings, RV.net - been lurking a while and figured "high time" to try and ask a question I've not seen discussed, although I may be "search fu limited"...

I'm looking at TC's to support my racing trips to distant events, 0.8k to 1.2k miles away. Will undoubtedly stay in a hotel at the event site (good showers are important!) but for nights along the way and for "office space" at the big events a TC really looks like the way to go. To my eye at least, the "boss" is not impressed with this idea...

My question though, as I review candidate TC's, is about LP generators and refrigeration and air conditioning. I don't really want to go to a gas 2.5kw etc as I don't want to have another thing to set up or carry another fuel, and I don't want to try and run a Honda or Yamaha on race gas LOL. I guess I wonder how important is it, really, to have a TC that is generator-ready; and given that, can I reasonably expect to run the fridge and a built-in genny (for A/C or heat) for a day on a tank of LP?

Thanks and regards,
- Jeff
(can't figure out how to do a signature yet!)

Ha! Why yes, yes I did! But thinking I best keep the cost of the rig below that of the race car, and since the race car of the moment is a C4 Corvette, that is one heckuva challenge. So I bought a CC/LB DRW with a 6.9 and a Banks Turbo. Of course I have to put in an overdrive trans to get past 45mph, but hey what the heck!

Glad I'm not the only one (nice rig, by the way...),

Ah HA! It was the PA Turnpike tunnels that made me think of this. Of course it's about placarded vehicles, and we now have proof that I just think too much.

Thank you very, very much!

(on edit) Since we have established that I think too much, I bought a dualie. Didn't want to sweat a rear tire failure with a 7k trailer full of race car. Of course in Massachusetts that's an automatic commercial plate. Hmmmm.

It seems to happen just fine to zero degrees. I'll be careful if I camp on the Hudson Bay in winter.

Did you run generator at this temperature.
Propane vaporize at -44F, but as I stated you need lot of heat to do it, so when small water heater will work fine below 0, high flow will drop the cylinder temperature down to -44F and no kudos.

Quite frankly, I don't think anyone gives it a second thought. They fill up before they leave, and go where they want using the most convenient route to get there.

Putting 10-ply tires on half ton trucks since aught-four.

I live 2 miles from tunnel, but only commercial fuel trucks are restricted (one of those crashed there about 40 years ago burning a number of people).
On BC ferries, where I go occasionally you have to shut off tank valves, what I do when driving anyway.
From what I know there is no restrictions anywhere in carrying small tanks as long as they are shut off.
We need propane for other things regardless, so you can't go without it, but too bad the propane generators offer such bad efficiency.
I still yet have to try how many hr my inverter generator will run on 30lb of propane powering AC.

I like your setup.
On my Fletwood the compartment is not only high above the ground, what is not a problem as I can (still) lift the cylinders, but there is minimal clearance for the cylinders in it and sliding them in horizontally require care to make the back feet fit into holding bracket.
Not only the switch over is on front of them, what require removal at each tie, but originally the floor at the door had sticking up bolt, that suppose to secure the tanks, but was scratching the paint on cylinders.
As I said I put longer hose for emergency and got rid of sticking bolts, but still pulling the cylinders for refill is not the job I am looking forward to do.

The big door you see on the left rear side of the camper holds the two 30# cylinders side by side.I'm over 6' tall and can easily heft them in and attach them even when the TC is on the truck, so swapping out the cylinders is easy for me. Four spare cylinders are strapped against the side wall inside my enclosed trailer.

Well,,,, my propane compartment is > 5 feet above the ground and it is design for horizontal position of the cylinders.
Sounds like you have vertical compartment?

My tanks are upright - If you have side mounted tanks, you have few options other than buying more of these to swap out. I have wooden or "Lego style" leveling blocks and put them under the 20# cylinder so it is the same height as the 30#. The retention strap should still hold it in place since it is the same diameter just shorter.

One of the reasons I went with my Arctic Fox was that they pack two 30lb cylinders into the camper. You can still run the shorter 20 lb if you run out and cannot find a refill location.

How do you hook up 20lb in your camper?
I could not fit 20 lb standing in my compartment and you can not operate them on the side like 30lb allow.
Having the supply hose deteriorating, I had new custom made in 6 foot length, so now have an option to reach cylinders on the ground, but that was not possible with factory setup.
