The wife and I just purchased our first Travel Trailer (Grand Design Transcend 26RLS) and we've got a couple trips already planned already. We thought it best that we stay close to home and that we don't stay out too many days. We even considered camping in the back yard, but the town we live has a lot of strange rules and we didn't want to tempt fate. Our first trip is to Smiths Point (Long Island) and two weeks later we head to Gettysburg for a couple more.Since it's only the two of us and we are only staying two nights at Smith Point, I'm thinking that I should not bother to connect the sewer line because the tanks won't be full enough to properly dump. I figured that we'd have to dump the tanks when we leave Gettysburg a couple weeks later. Am I on the right track? Is it okay to leave the TT with waste in the tanks for the two weeks? It shouldn't stink out the trailer, should it? Do I need to do anything special to treat the tanks? Funny but when we first entertained the idea of buying a TT and touring the country I thought that I'd be more worried about the idea of driving and backing up a travel trailer and now that the day nears, I seem more worried about sanitary aspect of it.

You have the right idea and will have no problem doing that. Enjoy your trips.

It's fine to wait 2 weeks and dump then. My preference would be to go ahead and just fill the tanks the first trip and dump then.

Does the trailer have a black tank flush? You could use that to add enough water to dump and clean the tank in the process.

I can regretfully inform you that most all of the northeast megopolis is now a police state. Usually, they be mollified by using advance notice to both the local establishment and your neighbors. Tell both that you want to do a day and night in the TT before you go anyplace. Most will not object. This is the best way to get to know how things work. If you run into resistance, then circle around until you find someplace that you can camp. Boat yards are pretty good bet. (I happen to know that there are a few on LI.) It does not have to be a "campground". Have a good time getting off the island. Matt - a refugee from the megopolis.

Get some happy camper for the black tank. Don't use that nice soft two ply toilet paper you use at home. Personally, I don't like leaving anything in my black tank, but that's just me.

Most dump before storing I believe. That said, if only waiting two weeks before your next trip, you can probably let it sit if you put something down to help control odor. I always dump before storing and then leave a couple of gallons in the black and grey tank to avoid any reside from hardening and beginning issues later. Water is your friend to move tp/solids out of the tanks when dumping. Alway try and dump when at least 2/3 tank full, even if that means adding water before dumping. Happy camping!!!

Since this is your first trip with a travel trailer and you will have a sewer hookup I strongly suggest that you hook up to the sewer and dump you tanks. You can do this slowly at your leisure and make sure everything works and you know how to do the whole operation. Get the tank 3/4 full or more before dumping. Do black first.

We just got back from our annual 4 1/2 month snowbird tour. We always use paper that is bum friendly - whatever brand. None of that sandpaper "RV" paper thanks. The black tank on the RV is a holding tank not a sewage processing device. Nothing gets broken down during the time it is in the tank. If you use a clear plastic elbow you can see all the lumpy stuff slowing out including wads of tp.

Enjoy your new trailer.

it also depends on how hot the our side temps will be. if it gets hot, the first time you flush the toilet you may be in for a rude awaking. Happy Camper will kill that smell if you use it up front before you ever use the toilet.

BB, we've gone 3-4 weeks before dumping. just keep some water in the black tank.

but my question is, you've been a member for 5 years now, yet you call yourself a beginner. how is that?

We have used this method successfully for years.
1. If the tanks are not full, fill to about 75%.
2. Empty the black tank first and refill with clean water.
3. Empty the black tank again.
4. Empty the grey tank to flush the sewer hose.
5. Put a small bottle of clothes soap (Dollar store size) in the black tank and put about 5 gallons of water in with the soap.
6. Disconnect the sewer hose from the trailer and rinse with clean water.
7. Leave the grey tank empty.
Using the clothes soap and water in the black tank acts like a tank cleaning as you drive. Also this wont leave you with the worry of smelling up the trailer when you use it the next time. The next trip just hook up the sewer as normal and dump when the tanks are full.
We do use black tank additive while using the toilet to break down solids and paper. Another thought is to use the campground bathrooms on short trips and not use the trailer toilet. The key with the trailer black tank is use plenty of water while using and flushing the tank while dumping.

No one has mentioned a clear 45 degree elbow so I will. Get a clear elbow so you can see when the water runs clear mostly when emptying your black tank and the water flows freely to make sure there isn't a paper clog. Install it at the takeoff and then connect your hose. I don't like to leave anything in my tank between trips because there is no reason NOT to dump when you have full hookup. Use the tank rinser and close the valve to let it fill up again and pull the handle to let it empty. DO NOT leave it unattended, be patient and careful so not to overfill when doing this.

The tank sensors that tell how full they are will be notoriously inaccurate so don't depend on them. Grey tank sensor not so much but the black will get fowled with paper and **** but you will know when its full. Happy camping.

Many campers believe that your black tank must be " surgically " clean after dumping . Why I have never understood . My way , dump it , add a couple gals. of water , hit the road ! Many will tell ya to clean , hose , clean again , add chemical , look inside with a flash lite ! Why !! Do not forget what it is for !

Always dump your tanks if you can. If you need to ad water to fill the tank more. Things happen plans change that trip in two weeks could change and your camper may sit longer then you thought so just dump the tanks and that is one less thing to worry about.

I'm in a Facebook group that is full of noobs. Some of them are absolutely convinced that they need to go through all sorts of trouble to dump and rinse, clean, deodorize, sterilize, etc. their black tanks. They think it's vital to use the black flush every time, pour in lots of chemicals, buy RV paper, the works.

It would be amusing except these are the guys who take a half hour to dump when the line is already backed up on Sunday afternoon.

I don't worry about the tank being so clean when on the road I can do that at home. I do want to make sure that my sewer hose ALWAYS get a good rinse.
