We have made it this far west, from Florida.  First 2 days were awesome. The AquaHot worked, after a fashion, but then decided not light up. 
It works fine on 50 amp as an electric heater.  I even used pre-heat, when it was 6F in Holbrook this morning. We are in Cottonwood for 4 nights and will be warm. I am wondering if anyone has used mobile service in this area for AquaHot?  We are not headed south. but north on Wednesday. As a last resort I will stop at Beaver Coach when we get to Bend.  But wouldn't mind getting it fixed here at the 1000 Trails. 
Thanks,
Mike
