We bought our 2200 in 1986 and it's taken us up and down the East Coast pulling our Harleys or street rods. That 413 pulls like a locomotive!
I converted it to 4WD right away because I had 2 Class A rigs before this 1972 and always took them right on the beach for fishing. We have a 2000 Winnebago Adventurer too, but we still love the 'old Dodge. We put a queen bed in the back, reupholstered the dinette booth seats and the green shag carpeting was replaced with a low pile carpet. The one thing that people love about that 1972 is the panoramic view with all the glass around the front. You can't beat that when you wake up out in Montauk, NY and have breakfast with a great view of the water all around! You can just see the Montauk Lighthouse off the back end of the Dodge. Enjoy your vintage RV!
