Hello, I'm replacing my wheel bearings in my new to me 1997 rockwood 1620. I purchased it this spring for $400, and had to replace the top due to dry rot. Surprisingly enough all appliances work exec the propane line to the furnace. The P.O. put a screw through the copper line from inside the trailer. Chases loot good, but driver's side grease cap was missing and bearings show slight signs of rust. Pulled bearings from both sides, neither side has any legible numbers. Just was hoping that someone might know the numbers, or have an original manual showing the numbers of the wheel bearings, before I spend my Saturday trying to match them by size. Thanks everyone.
