My wife and I just bought a 1996 Fleetwood Bounder and have found that it doesn't like to be filled at a "normal" speed. It takes almost two hours to fill half of the tank (approximately a 65 gallon tank). Is this common and is there a fix/solution to this problem? I also need to have the engine's A/C unit repaired or replaced. Because the RV is a 1996, can the A/C Freon that is currently sold, be used in this model? Any help or suggestions would be greatly appreciated. Thank you all for your time and consideration.
