I am looking to purchase a pop up camper for a planned tripped to Alaska from June to September, via the southwest. I have been researching pop ups through this helpful site and elsewhere. I am looking for a used, quality, 8 foot or less than 2000 lbs, lightweight pop up that I can modify to install an inside shower. I am willing to lose seating or counter space to accommodate the shower. I need a pop up for moderate off road use, so I would flip the axle or modify the leaf spring mount height, if necessary. It may depend on the weight of the pop up, but how do they fair in heavy wind during full extension? Does it get messy inside an extended pop up with heavy gusts of desert dust/sand? In fair weather, how long does it take for the canvas to dry out from rain before storage? During extended rain, does the canvas eventually allow moisture through to the inside? I am looking for an efficient way to heat and pump a couple of gallons of water for the shower. I am looking at portable propane water heaters, but have a generator for an electric water heater. I am new to pop ups, so if there are some considerations or factors I haven't considered, please let me know your thoughts.
