There is basically no difference other than the graphics. I looked at Thor products this past weekend and after what I saw, wrote Thor off of my list. Glaring quality issues in the cab of all 4 Axis products I looked at. Brand new vehicles with paneling patched and not cut properly leaving big gaps between the edge of windows and the walls. I said to the salesman, "If they can send out a product from the factory with such obvious flaws, what the heck is hidden that the customer cannot see?" Quality control seemed to be absent. I am going back to Winnebago where I know they have quality control, use lasers to cut panel walls, and can be trusted. Don't get caught up with all of the smoke and mirrors, look for the quality of the build, make sure the walls are constructed of metal framing, not wood, seems are welded correctly, you have side access to the generator (not under the back of the vehicle like in the Compass), screws have not fallen out of cabinets etc. Take your time to inspect heavily.
