OK, folks, I'm getting ready to button up the trailer project (got time now while the Cruiser is gone). Got the propane situation figured out, now I'm going to tackle the fresh water supply. I'm thinking a 15-12 gallon water tank (not too big, I don't want it *too* heavy) mounted low under the tub. Trailer is SOA, so I have space for it. I'm looking for your opinions on the following questions: 1. Plastic or steel tank? I had originally planned on going with a plastic tank. Bought one, had it in the garage for a while, decided it wasn't going to work. I like the idea of using a tank designed to carry fresh water in an RV, but the shape tends to be akward for my application and I can't figure out a way to mount it. Straps? Padded straps? some form of skidplate mount? Sources or suggestions for tanks? 2. Pump. Do I mount it on the Cruiser or the trailer? I'm thinking on the truck since I have a heat exchanger for an onboard shower setup, I could design the trailer tank with a connection for the shower. Pros? Cons? I don't have a good place to mount a pump on the trailer, and I *don't* want to run a battery on the trailer. 3. Filler/drain/nozzle. Years ago I had a chance to see Mike Bennet's modified M416 in Moab, he had a steel fresh water tank under it that filled through a hose that ran up the side of the trailer to one of the tub's corner handles. Very clean and simple system, but that might not work with mine. Any ideas/suggestions? Also, where do I get the hardware for this project? Anyone have any suggestions? Thanks, people, my goal is to have the trailer finished by the time the truck is done. This means getting the propane tanks mounted (decided against the permanent tank that I'd bought for various reasons) and secured, getting mounts fabricated for the badass airplane wheel chocks my wife got me for Father's Day, getting the water tank resolved, finishing the rewiring, mounting the new fully-enclosed light brackets I got and then sanding and painting the little fawker to match the Cruiser's new scheme. Oh, and I still need to paint the rims to match the Cruisers, too....this never ends!
