I wavered all over the place for almost a year while deciding which set up would suit me best. I considered everything: B or C, cargo trailer outfitted, p/u with camper, p/u with topper and a travel trailer and a van with a high top (that was never in question). Standing up straight was absolutely critical, I'd experienced living in a mini van before!!
In the end I ruled out towing anything, been there done that, found it limited my on the road freedom. I've never found a B that I liked the layout of, they all seemed lacking in storage and tight on space since the builders tried to include everything that would be in a big A into the space of a van so that went by the wayside. C's were nice but the gas mileage would limit my travel budget. A pick up with the camper would give me the travel freedom I want but my body is older and climbing in and out of the overhead bed unit put me off, also that there was no place to relax in one except at the dinette or in bed.
After mulling it over, changing my mind more than a few times, writing down pros and cons on paper endlessly, I came back to my initial thought of a full size van with a high top.
By doing the interior myself I get to include what I need and only what I want as opposed to buying a B. The bed is where I want it - not up top where I have to climb in to it like a truck camper. I have full standing height which was really, really important to me. I get the gas mileage, while not great like a car but still better than a C, that allows me the freedom to travel and stay within my budget. AND I'm not towing anything.
Once it's complete I'll have a bedroom, 2 pc bathroom, kitchen and living/dining area on wheels with more than adequate storage for all the things that matter to me. Okay, it will be a studio apartment more so than a full house but that's okay, I never close the doors around here anyways...
Make a list of what is really important to you then work from there!
