Holstein, have you made any progress with resolving your generator issues?
For the last few days we have traveled across the desert to visit Yosemite NP and Sequoia NP. Our generator has been giving us problems similar to what Stormdriver describes, quitting after 20-30 minutes or as soon as we pull into a blacktop parking lot, which sounds like overheating in my case. No fun driving through 110 degree heat with only dash air! The kids don't seem to mind the heat so much, but they thought they'd get to watch at least a couple of movies along the way. I bought an inverter for the return trip, but that won't cool me off. If anyone has some suggestions of things I could try for the generator before the return trip, I'd really appreciate it!
