My universal trailer/stacker had water tank and pump. I added a sink, use it all the time! Great addition. Although that may have to be a later addition to avoid the waste tank. I just drained mine to the ground, which a manufacturer may not be able or wiling to do.
Work bench, tool box and TV on the side with compartment for it are great. Air compressor too. Solar. Batteries for sure, but also 200 amp inverter as well so you can run 120 off of batteries. Lots of tie down points. Spare tire holder under the trailer like a toy hauler would be great. My spare is buried up in the top front of my stacker, pain in the ass to get to when loaded. Awning is nice
