Trailer Modifications

Our Sunline T1950 comes with a 24 gallon fresh water tank. It's probably intended to give you a chance to wash your hands and wash the dishes after a roadside picnic on your way to a full-hookup campsite - anything beyond that is tough to accomplish with 24 gallons. We've managed to make it last about 2 days with very judicial usage and military showers (2-3), but it's hardly convenient - and we didn't upgrade to an RV to forego convenience!



In the past, I did manage to extend things a little by bringing along a couple of 6G Reliant Aqua-tainers, but that's cumbersome in its own right because you have to lug them around, improvise a hose to pour them into your tank filler orifice, not to mention holding them up above waist height!

Therefore it was time to make a change. For this installation I decided to limit project scope to the fresh water tank only. My grey and black tank are both 28G for reasons that are completely mysterious to me, but I figured I'd deal with that limitation later on. Measuring the space it became clear that there are two ways to go - either replace the tank with a larger one, or add a second tank alongside. Adding a second tank would require a lot of hackery with Y adapters on all four connections to the tank, in other words - more points of failure. With that logic in mind, I decided to cram in the largest replacement tank I could possibly fit.
