To Dump The Fresh Water Tank ... Or Not?

New to this forum ... and new to RV-ing. My wife and I just purchased a new truck camper last Thursday ... an ALP Adventurer 86SBS. Believe it or not, we got the bare minimum of a walk through, so I have a ton of questions ... some of which I hope to find answers to by searching this forum. This is one I'd like a more immediate answer to, though:

??? The manual that came with the camper has a WARNING:Filling the fresh water tank should ONLY be done if the camper is on the truck, or if the floor is supported. Failure to do so may result in damage to the unit.

Does this mean that I should dump the fresh water tank before I remove the camper from the truck? If I take it off the truck while the tank still has water in it (the tank holds 45 gallons, by the way), that would be the same as filling it before loading it on the camper ... and the possibility of damage as stated above, wouldn't it? Here's the thing, there are going to be times when I want to take the camper off the truck and park it so that I could take the 4x4 into some rough terrain to do some fishing. If I've got to be dumping water before removing it from the truck, finding some support for the floor, then filling the tank again ... assuming I can even find a source of water in a remote location ...it's going to be a royal pain in the butt. What do folks do?

Maybe I could ask another question while I'm here ... seeing as it's sort of related to the first one? For winter storage in the backyard, I'm planning on pouring a concrete platform (ground level, of course) with ring bolts or chains set in the concrete that I can attach my fastguns to. This would make it pretty stable as far as wind is concerned ... and we do get some pretty high wind in this area. How high off the concrete platform should I set the camper with the jacks and should I also support it some way with blocking, saw-horses or some other thing instead of just leaving it up on the jacks?

  • Some campers are made to allow the camper to be removed with a full fresh water tank. These are usually basement models. My old Avion. Can't be removed with a full fresh water tank either.
  • Welcome to the Forum.

    No question, dump the tanks before unloading, or risk the floor being damaged, probably beyond repair. If the water tank must be supported, it is probably true of the gray and black tanks. My bet is you are not supposed to even use the TC if the floor is not supported. So, if you take the TC off the truck, you must sit it on the ground with floor supported.

    "What do folks do?" A few options.

    1. If only a week old, take it back and get a TC that better suits your needs.
    2. Leave the TC on the truck.
    3. Empty water from TC, and carry in five gallon containers. Set TC (floor) on the ground add water to tank. For a couple of days, you probably can make do with 10 to 20 gallons of water.
    4. Find out is the water tank is the only issue, and if so can it be reinforced to allow its use off the truck.
    5. Leave the TC on the truck, and tow a small 4x4 Jeep or similar.
    6. Get motor cycles, and tow a trailer.

    For storage, I suggest no less than 4 to 6 inches off the ground. The closer the better. I would use four pallets, stacked two high, and leave the jacks down with just a little pressure to help stabilize.

    Saw horses - no. They aren't sturdy enough.

    With my Arctic Fox, there's a recommendation in the manual on where to support the camper, so that's what I do. I use a stack of 4' wide 2x8s It's supported just a little bit higher than the lowest the jacks will go.

    Check with the manufacturer and see if they ave specific recommendations on where to support the camper when it's off the truck long term.
  • mines a MH ,but I empty the tanks each time it comes home. freash water fill when it goes out. keep your camper off the ground ,it,ll not draw moisture if its up some. and mouse proof your tie downs. tarp the unit , I,m for keeping the weather off the rv,s less chance of water damage.
  • Yes. the tank must be drained before leaving the bed of your truck. It is only lightly secured to the bottom of the camper, likely with two straps. those straps will not support the weight of the tank full of water.

    I can't help your other question...
