Hi, I am currently trying to decide what size bus I want. I really would like to have a shorty, but I need an area to shower. It doesn't have to be extravagant, just functional. What size water tanks can a shorty accomodate? I am thinking I want a futon for sleeping and sitting with aTV. Small fridge,with a microwave on top and bar size sink for kitchenette and the rv toilet, shower and water heater etc. Everything in one room. Sort of like the hotel rooms I get stuck staying in now. I travel 2-3 days per week with my job and would like to have my own space instead of dragging all my stuff in and out of hotel rooms all the time. Can I do this with a short bus or do I have to go full size? Any info is helpful. Thanks alot. Marsha
