DIY project for Generator rack

All the weight that you add to the rear will remove about the same from the hitch, and add all of it to the axles

Example: 200 pounds on rear + 200 pounds removed from the hitch = 400 pounds added to axles.

no way!!
the bumper isnt strong enough and 200 lbs plus on the rear is going to affect all kinds of stuff mostly related to tongue weight
put the generator inside the trailer or tow vehicle

your rear bumper is likely little more than a pop can. remove it and integrate with the frame. also expect tongue weight issues and sway problems. can you put it on the nose?

Be careful of the weight distribution.

All in, your rack will likely run 250lbs and depending on the exact spacing, I would expect around 150-200lb reduction in hitch weight.

Given your's is a relatively small & light trailer, that could easily push you under 10-12% hitch weight...too light of pin weight can cause handling problems.

Please don't bolt such a heavy rack the rear bumper...it won't last long.

Dont forget that 200+ pounds off the tail end will affect tongue weight. You will likely end up light on the nose and have handling problems if you dont compensate.

Man, I thought I was cheap$, lol. Most bumpers aren't very strong by themselves, the metal they use is usually a thin gauge. Try to attach to trailer frame and save some weight by letting your rack extend a little past your frame extension. Check your states regulations also as to weather you'll need lights, reflective D.O.T. tape, etc...
