Hitch Mount Cargo on TT??

You Should be fine I pulled my boat behind a "81 Prowler TT" for years on one just like that 18' Nitro bass boat. Until Someone told me I couldnt that it was to much weight I welded a cross peice on after that and then sold the camper to a guy from work that did the same thing and I saw the camper last summer pull in the campground all fixed up and sparkley pulling a boat on the hitch I put on. That had been pulling boats for over 10 years. That being said be smart if it starts to bend add some bracing and weld it to the frame.

Don't do it...the bumper is not designed to hold any weight. You need to weld a receiver to the frame rails. The issue is not the weight it's the bouncing that happens at the back of the TT as it goes down the road.

See my build thread on adding rear storage.

Any good machine shop will fabricate a custom receiver welded to your TT frame for about $300 parts and labor included. Your bumper is light weight aluminum only spot welded to the frame extents. I asked Camperworld to install the setup like in your pictures and the wisely sent me over to the shop that does all their welding work.

Isn't it illegal to carry firewood across State lines these days? Eliminating it would save a bunch of weight.

Most bumpers on most TTs are not strong enough for that kind of weight to be hanging out that far and bouncing around. I've seen more than a few that started to buckle or tear completely off of the frame where they're welded on. You will need some serious reinforcement. I used something similar to carry two bikes on the back of a TT and had to reweld a couple of areas where it attached to the bumper. Coolers and wood are going to weigh more than 2 bikes.

Do it and you can expect to see this one day;

Should I be concerned with support?
Do I "need" to the get a receiver that welds to the bumper?
Do I "need" to have the bumper reinforced?

Yes, yes, and yes. I used one of those for a short time for a bike rack. Wasn't long before I noticed cracks in the welds between the bumper and frame. I had them re-welded and gusseted and it still happened again.

After that I had a custom hitch welded to the frame rails and the bumper beefed up. Cost was $350. No more problems or concerns.

Post in the wrong thread perhaps?

My understanding is that if you do ANY mods to the frame if voids the warranty. The bumper mount idea has been discussed ad nauseum and the majority felt you do it at your own risk...see above picture. Suggest you come up with Plan B.
