Drill holes

Will it void the frame warranty if I drill some small holes in the back by the bumper? Want to drill some in the I beam to add a hitch.

Don't worry...adding the hitch will probably void the frame warranty anyway!

small holes - if you are installing a hitch - those arent gonna be small
I would call the factory but my gut feeling is like Dave said adding the hitch will void the frame warranty

This question was answered previously. Any modifications to the frame of a Forest River Trailer Product not done by Forest River will void your factory frame warranty. This includes anything attached to the bumpers of travel trailers and 5th wheels (even if only bolted on). Bike racks are OUT because the weight adjusted for the distance from the frame of a typical rack to the weld would limit your bike and carrier to about 10 pounds.

The limit for the 4 inch square bumper is 150 pounds the center of which is located within 6 inches of the frame to bumper weld. The factory spare tire and mount (if installed) uses up all that capacity.

Any holes drilled into the I beams will void your frame warranty (even if it might be stronger afterwards as the cross beam is pretty flimsy). The I beam on your camper is sized for the minimum strength required to support the GVW of the camper. Anything that weakens the integrity of the web will over time and road flexing cause stress cracks; further weakening the frame.

Would 4" PVC hose clamped to the frame also void the warranty?

All Warranty questions should be directed to the factory rep or your dealer.

My thoughts would be (based on FR's previous communications) that clamp on mods that do not penetrate the frame would have no bearing on the structural integrity (as long as they do not cause you to exceed the GVW of the camper).

As to how "I got so smart"? (School is still out on whether that is a joke or not)

Mostly by screwing up and finding out later what I did wrong and vowing not to be so dumb next time. Also a large part of asking questions HERE and getting great answers that I try to remember and "re-share."

Sorry to say; no. IMO

The tire may weigh the same as your rack and bikes but it is located within 6-8 inches of the bumper.

The bouncing torque of the lighter bikes on the long "moment arm" of the bike rack (about 24 inches or so on mine) causes twisting at the welds.

Like working a paperclip back and forth, the metal will "work harden" over time and just fail. If you are very lucky, a passing motorist will alert you that your bikes are dragging on the road before the bottom welds fail.

I have a nose receiver on the truck for it when we travel and move the whole shebang to the camper bumper receiver when we are in camp. PITA but worth the time and effort to move it back and forth.

Hi mstell, please consider updating your profile. You might
want to add a signature that tells us what kind of trailer
you have and possibly a city state and a handle (name)
so we don't have to say "hey you"!

IF you have a trailer you can carry bikes in the bed of
your truck. I have one of these--
Amazon.com: Racor PBS-2R Two-Bike Floor Bike Stand: Home Improvement
it's a floor bike stand. We set it in the front of my
pickup bed and put the bikes in it. Then a couple ratchet
straps from the bikes to the front tie down rings and the
bikes are solid as a rock. I've got several hundred miles
hauling them this way.

Now if you have a 5th wheel forget what I just said but
get a signature anyway!
