5th Wheel rear hitch

sorry no photos right now. a bit raining outside.
but i had a two in receiver mounted to the frame of my 2001 sunny brook fifth wheel.

think over kill here. but i use mine to pull a second trailer with a cj-7 on it.

but using at least 120 wall plate steel. make a plate for each side frame rail. using at least 6 or 7 1/2-3/4 in bolts each side to hold it together. make the plates at least 3 feet long.
(spreads any and all stresses out).
cross frame 120 wall 2 in (square or round).
cross frame at least three places (four best) to prevent flexing of a side twisting of the frame. best if 2 in square tubing. (easier to attach the receiver tubing).

add a triangle bracket from the rearmost part of the receiver. out -forward to the front of this assembly. (stress thing again).

gusset everything.

add wiring as needed for towing trailer.
i use a surge brake flatbed (would love a electric brake unit) so not wired for electric brakes..for now.

for just a bicycle rack not as much needed. but DO NOT use the factory rear bumper storage thingy. as it will fail.
amazing it can hold a spare tire.

Thank you for all the photos and advice!

Contact your 5w Mfg. and see if they mfg a “bolt on” hitch for your RV.

Hitchhiker stocks a hitch with a 2” sq receiver that “bolts on” to the mounting pads welded to the 5w frame. Complete with mounting bolts for about $250. I know I bought one for my HH 5w, then i made a rack to mount my Honda Gen to.

Maybe it could be adapted for other brands.

This is my hitch showing a bike rack on it. Fabricated and installed by a good welding shop.



And this was the reason I had it installed :) :

Looks like a simple piece of 4 square 1/4 or 3/8 wall tube.... Nice job......

Thats exactly what i did. To go along with the hitch platform i added two pads for the rear stabilizers to bolt to. Has worked well for nine years. Mine was designed to bolt onto the frame using three 3/4 inch grade 5 bolts.

You also have more weight to the rear but you are probably already considering that.

Becareful on what you do, you'd be surprised how easy it is to void the warranty.

Bolted to frame should be good for 300#

On stock bumper yes, I have been running for 5 years with my heavy bumper mod and 0 problems.
