Will be just the two of us, she has cats but they don"t travel well. At present just considering one day to one week (ish) long trips. Looking for bumper pull less than 20' self contained. With the uncertainty of this plague and random business closures, having my own immediately accessable bathroom has a certain appeal. My truck has a camper shell that I do not want to remove for a 5th wheel and it seems prudent to at least start out small. I have a decent range of skills from HVACR and electrical to computers and electronics so can usually fix anything I can get (or improvise) parts for. I like the Airstream design but they seem heavy and expensive, even ued. At the moment the Casita design has my attention. Are there any abnormal problems for a guy say around 6' 2" living/sleeping in one of these things?
