I know a couple that snowbirds in their camper van (also called a Class B, which is what a Roadtrek is) and loves it. They go deep into Mexico, boondock in Quartzsite, etc. I also remember there was a couple that had a website, this was before blogger, that fulltimed in a camper van and loved it. It can be done.
I also know a couple that started fulltiming with a camper van but it didn't work out so they moved up to a Winnebago View, a small Class C on a Sprinter chassis. That is working out for them.

Talk about timing.  After replying above I went to look for the blog for the couple I know who moved from a Class B to a 24 ft Winnebago View and found it.  I also found they are moving to a 34 ft diesel pusher and will tow a car behind it.  Looks like it didn't work out.  Their reasons were needing a better kitchen, but I am sure it is not the only reason.
Anyway here is Linda and Dave's blog,http://www.sandsys.org/wordpress/.

I definitely understand the attraction to the smaller option.  We currently vacation and weekend warrior in a 2000 Eurovan camper which we will give up for a 5er to full time.  We love the van and have put on well over 100k miles on it during our 10 years of adventures.  It is nimble and sure footed and can be parked in a 7' garage and normal parking space.  It does lack hot water, AC and bathroom facilities, but that has never been a problem for us.  The Roadtrek is definitely a larger vehicle with more storage and amenities than the Eurovan. 

We do have a couple issues with the Eurovan.  First, the storage is not convenient and is not sufficient for more than one sport (biking & climbing).  The closet in the van is on the side and is difficult to get to because of the backseat/bed.  Second, since we choose to sleep on the lower bed, it must be put away every day.  After two weeks on the road, this gets very old and if we forgot to get out the coffee pot the night before, coffee can't be made until both of us are up because the bed extends in front of the cabinet.  This latter has led to our number one criteria - a separate sleeping and living area.  :)   

Personally, I think it can be done, but as everyone else has said, it really depends on the person or persons if this is possible.  Things to consider are storage for clothes and any equipment, can you live in small spaces, will you have pets and is remaking the bed every day for the foreseeable future acceptable.  If possible, rent one for a week or two and see how you like it.

We had a Pleasure Way for a few years before going fulltime and absolutely loved it. Our longest trip was two weeks and we had some foul weather, but we just popped a movie in the DVD player and settled in. However, I knew I could not live in it fulltime. I need some space to do things other than camping. We did consider using it as our toad, but there was that pesky weight issue.

Sorry for the late reply, I just found this site looking for other Roadtrekers who blog. I can speak to this question directly since my wife and I full-time in our 97 Roadtrek 170P. It is very comfortable, has more than enough room and honestly, we wouldn't trade it for any other rig. I have made quite a few mods to it which can be seen on our blog. I am currently making a few more changes to make it even more comfortable. I am happy to answer any questions anyone has on this. Feel free to email me anytime.
