That era of WW should be checked for front cap leakage. Go in to the left front exterior storage compartment and under the sink in the bath and feel for soft floor. The fuel pump used for the transfer station used plastic gears that can swell if ethanol based fuel is used without treatment.

We loved the amount of garage in our FB2200 and typically were over 11k lbs when loaded with water, supplies and toys. If you find this to be a good cared for unit, you will need to watch what you pack because you can fit more than what the wheels and axles can handle. We sold ours because we needed more space for the toys we started collecting.
