Good to see the group here seems to have managed a lead resulting in ownership of your own rig! Gone is the anxiety of the search, and now the joys of ownership... Good for you!
littlehody,
Grampswrx and Brian W are right...find the a van with living quarters that fits your needs and convert to 4X4.
Get your own conversion done and it's all new. Anything other than quigley. I have one. Not an easy fix when front hubs have an issue and your not right next to the Quigley parts room.
You stated "I am open to seeing any/all options". Eliminating 2WD and doing your own 4X4 conversion is not being very "open".
