ATF: North Trail - Bumper Specs

[JWalker]

I have a 2011 North Trail 29RE 5er and I wanted to know what the weight limit is on the rear bumper. We would like to add a bike rack to the bumper. It currently has a spare tire attached.

I don't know if this is the place to post this question. I believe the North Trail 5er are made on the Sundance line.

Thanks for the help
Jamie
