After lurking for a while on these forms I joined today..
We just picked up our 2017 Roo 183 and while reading the owners manual it said adding anything to the rear bumper may void the warranty. Does anyone know why this might be ? The rear bumper doesn't look to be the strongest but other than that I don't see a reason not too. Has anyone ever been denied a warranty claim for a bike rack ?
My plan was to weld a strip of 3x2"x3/16" angle along the inside of the bumper to connect to the stubs of the frame sticking out then weld a 2" receiver tube to that and the bumper so I can simply plug in my existing bike rack. I plan on filling the front battery carrier which should keep the weight biased towards the front. I also may change out the exisiting 20LB propane tanks to 30 or 40lb tanks depending on how fast they empty and just to make sure I have enough tongue weight.
The bumper is not even 16 ga and no amount of reinforcements will make it hold up to bicycles bouncing on a cantilevered rack. The frame will not support a wd hitch being used for a bike rack. DO NOT DO IT! Find somewhere inside for the bikes.
Thanks for the replies. I knew the bumper was weak but I hadn't crawled underneath to see how weak the rest of the frame was, otherwise I would just weld some 6" square on as a bumper. I will probably just rig up something for the inside, wife be damned lol
Here are some pics and a diagram of the receiver I had put on my Roo 19. I had it 3 yrs and I'm sure it's still going strong. I've had a similar one put on my Mini Lite. People will tell you about "voiding your warranty," but I'm pretty sure my frame is a lot better NOW than it was before!
