The Trucks are either a 2000 F350 Crew Cab dually with a 7.2 diesel, or a 2004 F350 Super cab SRW with a diesel also.
I will be pulling a 2005 Holiday Rambler Alumascape 30' 5th wheel.
I have a 2005 F350 Crew Cab dually with a 6.0 diesel, but it sits way to high, and it would cost a small fortune to bring it to stock heights.
I will be doing local pulling of the 5th wheel roughly 50-100 miles to the campground 4-8 times a year, without any mountain terrain.
