I plan on buying a 2005 30' Holiday Rambler Alumascape. Would an F250 deisel Super cab be a good truck to pull this with, or should I stay with the crew cab dually?
If you are mostly going to use the truck for towing, I'd go with the older Crew Cab dually. It will give you more room, and those 7.3s were great engines, just a little noisey. It appears you are familiar with diesels, and the problems that can be expensive. The 04 350 Super Cab would work. I tow a similar size FW, with a 13 Super Cab. Just two of us, works great for me.
