APU or alternstive for 2014 cascadia

Own a 2014 cascadia and im looking for options i can do to heat/cool the cab without running my truck all night.

I know you can have an apu unit installed but lets face it, that isnt cheap.

So ive been thinking about just slapping a generator on the side of my truck and running an extension cord inside to a spaceheater and mini AC unit.

Thoughts? Any other options? Maybe a cheap APU?

Thanks

 

Yeah i went ahead and bout a 3500watt generator last weekend but have just been debating. It was $330 for it. Ive found used APU's for $5k. I can build a box and mount on the frame to hold my generator and noone can steel it. Was going to run its own exhaust as well and just run an extension cord inside a truck. Seems easy enough

 

How well do those actually work and how do they work? Off fuel or electric? And are they only heaters or AC too?

 

Well I decided to go with the generator. I welded up a custom box and mounted it to the frame behind the cab on the passenger side. Generator is bolted inside the box and has a lock on it. Ran a weather proof box on the outside of the box to run an extension cable inside the cab. I went this was becuase I liked the idea that if it got to cold out, I could plug the block heater in to help keep the truck warm at night.

Generator is fairly quiet when box is closed. 3500w generator. My last part of finishing the project is attaching an exhaust pipe to the generator and running it outside the box. Generator dies when the lid is closed (even with vents) due to the box fillin gup with exhuast fumes.
