Instead of hanging it off the back, which sounds precarious and would look rednecky, how about above the front axle between the frame rails? That's where I'll be putting my Pioneer 12K condenser unit of my minisplit - I previously had my electric air compressor there, but the condenser unit will now have to go there instead. I don't want anything visible from outside, it will be protected from rain and pilferage, and it won't use valuable underfloor storage space. Surprisingly, my little air compressor hardly got dirty at all after several years there: the front tires shoot their dirt and water back behind them, so the space above the center of the front axle remains fairly clean. There's plenty of airflow there, and it will fit (just) under the floor with enough space below it for the axle to do its up-and-down thing without hitting it. I made a simple support from two pieces of hefty angle iron for the air compressor, so I'll use the same design for the A/C. It wouldn't be easy getting a 75lb condenser up into place from underneath, so I'll cut a hatchway in the floor above it to drop it easily down into place - easy!

Welding!

But I suggest that you get over your fear of welding and learn how. It opens up so many new worlds. A cheap stick-welder is all you need to get started.
Thanks man. I still need to put an extruded metal 'screen' on top and was thinking of having someone weld it in. Maybe I should get a little welder and try! It would be fun to do!

Time for some youtube university!

My plan is to mount my mini split condenser on heavy duty drawer slides that will allow it to slide out from under the bus skirting on the passenger side forward of rear tires. I will only use the mini split when parked so it can live safely under the bus when not in use. I will have to get flexible line set made but that may be more durable in a mobile application than solid lineset. The challenge may be finding an evaporator that will fit between the bottom of the frame and the bottom of my skirting.

A quick google search for "flexible lineset" kept showing what looked like normal bendable lineset. But this video is a whole 'nother story:



Wow. That's a GREAT idea.

I should be able to get automotive lines made in the correct size. They would have to be rated for the higher pressure of r410a.
