I've got what I think is a good deal on a freightliner with a 515hp detroit 60series and 13speed. I really like the idea of outfitting the sleeper a bit better and to match the guidelines with the NC DMV list of requirements for an RV conversion. Put a little flat bed on the rear and a gooseneck ball for towing the 2 jeeps, maybe a golf cart or rzr on there sideways. RV means exempt from CDL and weighted tags. I did this on my military trucks in the past (2.5 and 5 tons) for the same reason. I've seen a few rigs like this rolling down the highway with nice big stickers on the side that say private rv not for hire so I know it's been done by others. I just want to go normal highway speeds while towing 2 jeeps without melting the truck down and a semi seems to be the cheapest option.
