I would not want a vehicle that I had to worry about breaking down anywhere much less with a camper in the bed and many miles from home. I would also never choose a heavy diesel powered truck as my daily driver with the poor fuel economy and with diesel costing more than premium grade gasoline.
Unless you are towing a very heavy 5th wheel trailer there is no reason to have a diesel engine. A gas engine with a 4.10 rear end is going to do the job equally well 99% of the time. A diesel for a camper and most towing is a nice to have and not a need to have item.
My daily driver is a 45 MPG Prius that uses regular grade gas. The Duramax truck is used to haul large stuff that will not fit in these cars and to haul a camper and for towing. The choice of the diesel engine was to get greater range from a tankful of gas when "camping" in the western USA and even then the 36 gallon capacity is marginal and I will be changing out the factory tank for an Aero 52 gallon tank next month.
