Not sure if its included now but before they would also charge for the installation/sealing of the camper. What started out as an "affordable" option went too high with all the dest/install/sealing/fit kit fees. They are a great camper though. Just priced a bit higher for us. Now in hindsight...
Me! it wasnt hard at all if you lay out a design. it wasnt cheap but it was cheaper than the fully built systems out there that some companies offer. way cheaper in that aspect.
