I'm looking for suggestions on HVAC aftermarket products for my 2007 E450 dual alternators and batteries. Would solar be a good investment, or a generator? Possibly one that has heat for the rear in the winter, although I do have coolant lines going to the rearbut I'd have to keep the engine running.
I carry multiple rescue animals in my bus and the front AC works, but the rear needs a new compressor, plus I need AC when the engine is off. We're a non-profit so,of course, we have a budget.
