Funny that's what I made my doghouse out of but its all on hinges so it folds all down for service.

There are many ways to make a doghouse.

Sorry that I didn't read all the replies, but---
I'd suggest NOT using a gravel floor unless you have a real good moisture barrier underneath. Moisture will be sucked evaporated up from the ground every time the temperature changes. Since the air that causes it will be warmer that the metal surfaces, that moisture will condense on said metal. Not good. Even worse if there's metal in the roof structure. Then it can "rain" inside the enclosure.

There would likely be no fire retardant material in it. It is designed for water piping inside only.
I think you're right - I assumed it was by the company because they used their pictures and all of their sales media but the location doesn't match up (they are both in Nashville but one is about 20 miles outside town).

Still might be worth trying to pick up if I can. I just don't know how easily the insulation would be removed - I know it is both glued and framed into the enclosure :/

The insulation will help to prevent condensation, both on the inside of the enclosure as well as on the generator itself. As long as the hot cooling air discharge is ducted directly outside, and fresh air is simply allowed in through another vent, there's no way it's going to get too hot in there.

That $200 enclosure is definitely worth checking out.
You could always cover the insulation with 1/4" thick cement backer board.
How noisy will it be inside

It is a surplus unit. Did research on the insulation and it is flame retardant - the only consideration for it is toxic off-gassing when burning which outside the house is not a huge concern - the material is rated for indoor home use too.

I'm going to set up a time to meet with the guy and I'll update here! I'd be curious what a new unit costs from the company - might even still be a good deal for someone else in a similar situation.

I'ld add a piece of sheet metal as a radiant heat shield in areas by the exhaust. Standing off of the inside walls/ceiling. Just like they do in cars near the muffler and converter.

For what it is worth, the best thing I did for my stand by JB power plant was to build a 8 x 12 wood frame shed with a poured concrete floor and vented gable ends and an electrically operated window shutter for cooling air. I also located the muffler inside the shed to prolong its life. Been operating successfully now since 1970. Want more details?
