When my Kohler was down, I mounted a Champion pull-start generator to a platform Hitch Haul and ran the shore cable to it while i drove down the road. It got us to Yosemite and back that way and was a very viable alternative. Plus it freed up the compartment for additional storage. The whole setup didn't cost $350.
