EDITED
I initially had the rough cost here but realized it will be out of date very soon and this thread will be around for a while. I would suggest contacting the sales guys at ITB in Coaldale AB for an accurate quote.

Guido, I think a lot could be done with a used moving van like a U-haul or even an refurbished ITB box. Unfortunately our timeline with this build was to get it done ASAP so we had to outsource the whole unit. I think if a guy had some time he could retrofit a cargo box to a pretty darn nice camper. I know Sarconcepts built a very nice camper using one. The beauty of this type of build and any other cargo box build is that it is all done for a 34" frame so totally universal from one heavy duty truck to another.

The way the camper body is constructed, it will last a life time. You can jack the camper body off of the chassis and slide new trucks under it for years to come.




Unless you have done a thorough budget it's sobering how expensive it is to do a top drawer camper. My hunting partner had ITB do a flatbed camper box for his Fuso Fg. He did some of the outfitting of the box and contracted a potion. In the end it cost about double what a standard Alaskan camper would cost or in the same ballpark as an XP camper. The upside for the ITB system is it should be good for the life of the owner.
