I have a '97 winne adventurer 34RQ with the Ford 460...everything works and runs like a top...the roof is fiberglass too. no seatbelts on the dinette but have them on the barrel chair and couch! Happy, Happy!
By hot, I mean they are OK...they are not HOT temperature wise...sorry....the batteries are 3 months old.....just got back from 4 days camping...everything working OK, until tonight I went out to hang up some clothes and the door light switch didn't turn on closet light. then I find NO 12 volts anywhere. .BUT the chassis battery is fine can start engine etc...only the coach batteries not working...
Get a gallon of ammonia...clean off the old wax,etc...then use Red Max/Zep or Poli-Glo....lasts and lasts! All polimar finishes. 4-5 coats first year the a coat or two thereafter.....the PoliGlo is made for marine finishes (Boats)works wonderfully. Not cheap!
It doesn't use any of the refrigerants that you listed. Besides, its a sealed system and you shouldn't be fooling around with it. :B
I have the equipment for both R-12 and R-134 and have charged lots of autos! Thanks!
