I found my loaded 2015 RAM 3500 SRW Laramie Longhorn Mega Cab Cummins Turbo Diesel (in 2016 one year old) with 28,000 miles on it and purchased it for $48,000.00 with FCA 8 year 120,000 mile warranty (from a dealer with 1.9% financing). This truck is not the IDEAL camper truck (it is for us with our Outfitter Apex 8), but just to show you what you can find for the money. I think you'd be able to find a really fine 2013 or later RAM 3500 CTD with all of the bells and whistles in the 40's range and a really descent used camper for about 20K. That will get you all of the haul/tow capacity you'll ever need. JMHO
