I have a 2020 Grand Design Imagine. Would it be safe to place a bike rack on the bumper to carry about 80 pounds of bicycles?

What does the manufacturer say? Most say “no.” Look in your owner booklet. It’s not just the total weight…it’s the bouncing weight.

GD Booklet, page 159…

Rear Bumper
The rear bumper of your RV is not designed to carry cargo.
• Items that extend beyond the bumper will place undo strain on the bumper.
• Over time, weight added to the bumper will cause damage from the motion created while traveling.
NOTICE
DO NOT add items to the RV rear bumper. Add-on items will eventually damage your bumper. Damage caused by such aftermarket equipment installation or improper loading voids the Limited Base Warranty & Limited Structural Warranty.
Exterior Care
• Extra weight behind the axle may reduce the hitch weight (leading to adverse handling conditions from wind gusts and/or passing traffic).

Thanks for that. It's been a long time since I actually LOL'd at anything on this forum.
Oh, I laugh at certain chronic, ego-maniac posters from time to time (today even) but not threads.

The no poster did not elaborate however no is correct. The OEM bumper is not sturdy enough to support a bike rack. You can get a welder to reinforce the bumper/replace it with a sturdier bumper or have the welder fabricate a rack or hitch to carry bikes. Even then you will need to be concerned about tongue weight and the adverse effects of carrying the
weight hanging off the back.
It can be done but it not as simple or straight forward as installing an off the shelf bike rack

If you have "standard" skewer fork mounts, I carry my Trek's on the dining table inside the camper.

I mount these forks to a 1x4, clear off the cushions in the u-shaped dinette, and then put a 1x4 on each side. I've also screwed in 2 eye hooks opposite the fork mounts, and am able to bungee cord my rear wheel to the eye hooks, while the front fork goes into these mounts:

This has been argued to death in the past.
It’s not the weight you have to worry about, it’s the swaying back and forth that breaks the welding. If you can anchor the top of the rack to the trailer and stop the sway it should be ok.

It depends on the gauge of the tube used for the bumper, and how its attached to the frame rails. Lots of variables. About the only thing that is kind of common is if its a Lippert frame most likely a bad idea without a lot of added reinforcement and there is a 100% chance your Grand Design has one.

All of that said I see plenty of folks with bikes hanging off of rear bumpers and have yet to see a pile of them on the road other than pictures posted in RV/camping related forums, and its usually the same picture that has been posted thousands of times for 15 years LOL. Heck I seen a Grand Design TT picture where the entire rear wall fell off on the way home from the PDI.
