We just brought home a 1993 Fleetwood PUP. It needs cleaning and some repairs. Where do we start? What are the things we must check and take care of asap? What can we do to make it more comfortable for us all? It is a very basic, small model. No toilet or shower. It has a small sink, stove, dinette, two pop outs, very little storage, several canvas patches. Our sink needs a new diaphragm-what does that mean? The curtains are in shambles. How do I replace them using the existing clips? I believe they are C clips and the curtains are/were sewn directly onto them. We have 4 boys and are excited for new adventures with them! Thanks for your help!
