Hi new to forum, kicking around the idea of purchasing a new van to convert into a class b camper. I don't really need all the comforts of the ones on the market; shower,flush toilet,stereo etc… seems like a lot of weight and space to waste. I'd like to stand up and have the amities of one of the older vw westfalia campers, sink, stove, heater, bed, seating, porta potty and for two people. Would the 1500 work or would I have to go to 2500 for the hightop long?
