RV Repair: pace arrow water heater, hot water heater, pace arrow

Question
We have recently purchased a 1986 pace arrow motorhome.  The hot water heater has busted and we are having difficulty finding a replacement.  Have they upgraded the original model?

Answer
Yes they have  you should be able to look at water heater online or get them from a good dealer if it is and atwood you can buy just the tank if the rest of it works if you have a suburban then the hole thing will need replaced. look for the model number if it starts with a g then its an atwood  if not prob a suburban. The model number wont be the same but tell me what you have and Ill get you the new model number.
thanks
