Kimi,
I started with a used 37-foot class-A. It had all the convinces but there were several things that I didn't like.
It was a money pit. I had to replace the fridge, the washer, the hot water heater, the sofa, and a window. With all of this the total cost was about $11K. Then I had to replace all of the tires, a starter relay, awning, all of the batteries, and the drive shaft. We enjoyed it and took it on a trip up to Alaska, but when we got back, my wife informed me that she didn't want to drive anywhere long distance again. So I put it up for sell.
This past year I still wanted to travel, but didn't want to take the big rig out if I was going by myself, so I chose to go the Prius camper route. This worked fairly well but was just a bit too cramped for me. I got tired of always having to put on my pants while sitting down. Also, cooking outside gets a bit old because of gnats. If I had chosen to continue car camping, I would have gotten a "cooking tent" so that I could fend off the bugs. While it was cramped, I took it on trips to Padre Island, Big Bend, Tombstone, Moab (Arches, Canyonlands), Bryce Canyon, Monument Valley, and Rocky Mountain NP.
I recently purchased a class-B Travato 59K. It's a bit more expensive than what most of the folks in the forum have, but I decided that I could afford it once I got the class-A sold. I've already taken it on the road for a couple of reunions as well as spending some time in my home town. I was seriously looking at one of the Wayfarer Van conversion kits, but I decided that I needed a bathroom and not just a potty-porty or a bucket. If I were a bit younger and single that's the direction I would have gone, but I still want to be able to pick up my wife at an airport and let her stay with me once I reach a destination. I doubt that she would be agreeable to a bucket.
So I guess the key is to think through what your goals are. Once you have done that, then think about what type of rig would best fit those goals.
