We are in Grandview Missouri, pulling our '73 Trade Wind on her maiden voyage. She was an easy pull from Denver across Kansas barring a few glitches with the tow vehicle. After arriving here we discovered our new battery was not holding a charge and the 12 volt
system ( heater, water pump, lights & radio ) worked for short times then not at all.
Hank Switched to a different battery and it also was drained of charge with in a few hours. After a few days of searching for solutions we discover Country Campers of Grain Valley Mo. & Owner John who has a mobile RV repair. He came to us in Grandview, quickly determined the 40 year old uni-volt had several issues that even the previous owners tried to work around. Of our options, we chose to have him install a new Progressive Dynamics PD9100, which he did the following day. It took him about 3 hours to diagnose, then install at a cost of $600. This may sound high but we were delighted! Now everything is working well!
We knew before we left that the Uni-volt was not re-charging the battery as it should but could find no one in Denver that wanted to deal with a 40 year old Airstream before well- into October; if at all.
