Heck yes, 2 RVs, why not 2 trucks. You could go older or newer on the future diesel and 2 wheel drive or 4 wheel drive. I seriously would not modify your engine for more power. I think you could find a nice used diesel truck for $20,000 or so, but if you're looking for an excuse for a new truck, $65,000-$70,000 will buy you a pretty nice diesel truck. Of course once you upgrade the truck the DW might also start looking at 40' fifth wheels, just saying.:E Once you go diesel you never go back!
