Hi everyone, This is my first post. DH and I just bought a used RV class A. This is our first RV so we are new to everything. Our RV is a 1999 Dolphin. I haven't seen too much on here about Dolphins, but we like ours. It seems to be in good condition. We had our son, who is a master ford mechanic look over the motor and he said it looked good. The only problem we've had is with the slide out. It's fine going out, but makes a grinding noise when we try to bring it back in. My DH goes out and sort of lifts up and pushes in while I turn the key and then it goes in. He's good at fixing things. Anyone have any advice on this problem. I've been telling my DH to post on here, but he's never got the time, so you will have to bear with me.
