I tow a 251 Checkmate convincor with mine. I added air lift bags to the springs and what you get is a tow vehicle that eats up half ton trucks!I'm serious, I have towed my 5000 pound rig with a 1999 Z71 Chevy and this Fleetwood puts it to shame, it's a torquey ole girl. With 150000 on the clock it runs and performs flawlessly. Normal parts, egr, ball joints and such, no biggie. Very dependable, will buy another!"
