I have a new Cherokee 27L TT. I am considering making a aluminum checkerplate enclosure and mouting it on the rear bumper to carry my Honda 3000i generator. It is just to heavy to be lugging around any more. Anyone else have this done? Are there any weight concerns should I have by doing this?
bantam1960's correct. Most TT bumpers are designed to withstand rear impact, not support loads. Also, when you put weight on the extreme rear of the TT, you certainly have reduced your tongue weight, probably much more than the generator + rack weight... Insufficient tongue weight can make for some scary, even dangerous, towing experiences.
I saw 3 brand new trailers for sale at a Camping World parking lot. They all had Honda 3000's on the back bumper. Nice mount too with locks. I have 80 gallons of holding tank capacity(640 pounds) at the back of my trailer. 150 more won't hurt anything if your tanks aren't full.
Good question and one I can answer given I've just done this modification.
I mounted my Yamaha 2800i on a steel, welded frame made out of 2" L brackets. The bottom is an open mesh grate. The entire frame weighed in the 20+ lbs. range, add the 64 lbs. of the gen. and the 10 gals. of gas carried and I was in the vicinity of 150 lbs. hanging off the back of my TT.
I was leery of hanging that much weight on the bumper so, I had a friend weld 2" C channel (roughly 2' long) extending from the bottom of the 4" bumper to mid trailer, along the frame rail.
As far as handling went; It was noticeable! Not uncontrollable, but noticable. First, I had to redo my hitch set-up in order to have TT and TV level, secondly, too offset the loss of tongue weight, I shifted my packing arrangement to have all heavier items, forward.
The end result was satisfactory in regards to pulling the TT however, as said before, I could "feel" the rearend of my TT. Not as in sway (tough to describe) but suffice to say...it felt different.
FWIW: I use the Reese Dual Cam anti sway.

Many manufacturers rate the carrying capacity of their rear bumpers. Ours is 150#--since we have two mounted spare tires we are that point already. I was thinking of this generator rear mount problem yesterday while following a vehicle with a fairly large electric wheelchair attached to their bumper hitch on a carrier. That wheelchair was definitely flexing up and down. Wondered what they felt in the vehicle. You also need to be careful of attatching a receiver to a lightweight frame--again the up and down flexing. There was a post awhile back about this--bent his frame.

I have done this mount with my generator. The bumper of my trailer is reinforced more than some others I have seen. It is mounted with three pieces of square tubing, joining to the bumper either with a receiver tubing or with U-bolts.
The tongue of my trailer is pretty heavy to start with, so I was not concerned about removing some of the tongue weight.
pm me with your e-mail address if interested, I have pics of the way I did it. Basically, fabricated a "hitch" on the back of the trailer (mounted to the frame, not the bumper), and inserted a generator tray with gen and fuel. As mentioned by someone else, there was a difference in handeling, but after adjusting the hitch, not a problem. I would not hang a generator off the bumper, just not designed for that kind of weight.
The above is just my .02, which is normally only worth .01 (just ask my wife ">)
