Well, after having an eb 50 quigley for a few years, I had decided that I needed more room to haul kids, etc. So a couple years later, here is the new rig:
2014 Quadvan rb with SMB pop top, set up as a flexible passenger or camper. I went with the v8 this time and I really like it for this application, it drives a little peppier around town, etc. The fuel economy is not what I was hoping for but I suppose thats not why I bought an SMB! Getting ready to do a solar/12 v system and purchase an Engel or arb fridge soon.
I must say that the quadvan does indeed ride nicer on the road, but have yet to take it out on the trails.
and...The kids love it!
