I've been ciphering for a while, trying to figure out where to stealth install our 30 Amp Huges Autoformer. At first I wanted to put it in the trunk, but that was going to require too many holes, and disassembling the Autoformer to route the cable.
Today, I found a home for it in the utility bay. I mounted it on a plywood base, holding it in place with 3 1x1 cleats and an aluminum strap. The base is screwed to the plastic tub floor, and serves to distribute the weight of the autoformer.
The Hughes installation kit includes a new female outlet for the park cable. I mounted that above the generator outlet. The idea of the outlet and pigtail on the autoformer is that you can easily bypass it if there are problems.
