Mount 100lb mini-split condenser to rear wall?

I have a Coachmen class A and want to mount a 100lb mini-split to the rear wall. Is this too much weight? I know some people use a hitch carrier but ours is occupied. And this RV has no square bumper to put mounts on.

I would use one of these wall mount kits. Maybe this exact model, maybe one like it.

I built my hitch for bikes so I used 2 x 4 x 1/8 tubing... the iron yard had the remnant already cut. The hitch is all welded but I bolted the completed hitch to the 5er frame so I didn't have to weld next to all the flammable materials. It won't go anywhere with 6 - 5/8" bolts going through the 2 x 2 x 1/4" tubes that then go into the heavy backing I put inside the frame tubes.

Most situations are unique so there is not a simple answer. It is welded to the frame. Also made up an undermount for the spare and after this pic was taken I added support from the uprights to the tire mounting bolts to stabilize the uprights. For welded steel there was a surprising amount of flex.

Also do not want the framework sticking out any farther than needed as it will scrape on inclines/declines. I have it out that far so as not to back into something and damage genny box.

Forgot to mention the rear hitch also hauls the spare tire.

Iโ€™ll probably weld something to the frame for all three.

I built a rack on the back of one of my 5ers, all welded to the frame, to haul a 10' pontoon boat. A small rack for a mini split and bikes would be cake! I recently built a bumper on my Sunny Brook so I could use my old bike rack. I'll post a picture. I bolted this one to the frame and it might give you some ideas.
Mini split companies need to work on rv systems. They'd sell like crazy, with their amazing seers. The cassettes and multi zone systems have been around for a long time... They just need a low-pro roof condensing unit. Craig

3 point mount on my little Toyota for a generator box. No flexing or torque on RV.

Not sure about the mounting, but I love my mini split in my man cave. Super quiet, and efficient.

It would look really bad, and no one would buy it when you decide to sell it.

This style of heat pump is a far nicer looking option and won't destroy the rear wall (or resale value) of your RV


That's a conventional air conditioner with a heat pump for winter but I really need to save electrical costs so I'll think of something. Maybe weld mounts down into the frame, I dunno.

I have a friend that mounted his to his rear bumper. He was more than impressed with the units performance.
