Race Ramps Super Duty Service Ramps for Trucks and RVs | RR-STR
30,000 lbs Per Ramp, 48 lbs to Carry
Service ramps rated for a motorhome are usually cast steel, live on a pallet, and take two people and a hand truck to move. Which means they get used once and then stay wherever they were dropped.
The Super Duty Service Ramps carry 30,000 lbs per ramp, 60,000 lbs per axle, and weigh 48 lbs. Race Ramps rate them for trucks, semis, and RVs, and one person moves them.
Each side is 96.5 inches long and comes in two pieces: a 68 inch ramp with a 6 inch lip that connects to a 34.75 inch cradle stand. Once the vehicle is up, the ramp lifts away from the stand and the undercarriage is open.
Lift is 10.25 inches on a 15 degree approach, deck is 11.75 inches wide for tires to 11 inches. Sold as a pair. See all ramps.

Super Duty Frequently Asked Questions
Can foam really hold 30,000 lbs?
That is the rating Race Ramps publish for this model, and it is why the Super Duty exists as a separate product from the rest of the line. Solid high density foam is load bearing in compression, and the wide base spreads the load rather than concentrating it.
How does the two piece work?
The 68 inch ramp has a 6 inch lip that locates against the 34.75 inch cradle stand. Drive up the ramp onto the stand, then lift the ramp section clear so it is not in your way while you work.
Will my RV tires fit?
The deck takes tires up to 11 inches wide. Most Class A and Class C coaches run inside that on the steer axle, but measure yours. Dual rear wheels need checking as a pair, so call us with your axle configuration before ordering.
Can I go under the vehicle?
Chock the wheels still on the ground and set jack stands before anyone goes underneath, exactly as you would with any ramp. Race Ramps also advise caution using these with a trailer or a three wheeled vehicle.
Is 15 degrees too steep for a motorhome?
Ground clearance is rarely the problem on a truck or a coach, so the steeper angle buys a shorter ramp that is easier to store. If you have a long front overhang, measure it against the 68 inch incline and call us if you are unsure.
