I like the XP. Marc really engineers his products to perform and they seem to have quality built into them. I was impressed with how much room and functionality the XP-V2 has on small truck frame.
There is a big following of Four Wheel Campers for hardcore offroad truck camping. But IMO, just crawling in and out of a FWC one time was enough to turn me off of them.
One of your wish list items that caught my eye was the passenger side entry. Are you planning on towing? XP and Outfitter's Juno are the only one's I know of with standard passenger side entry.
Seldomseensmith brought up a good point about side entry departure angle. The Juno will have a bit more overhang. The XP still has great departure angle and passenger side entry.
