I didn't see where the age of the CC was mentioned so my guess of a value would be wasted effort.
But the things you've mentioned would make it a no sale for me unless I could get it for a bargain basement price.
No slides? Poor resale value. Only starting the engine without taking it out on the road for 20 miles or so each time? I'd not want to own it for long. Might make a good flippable RV though, if I could get it at a low enough price. Peeling clearcoat? Very much $$$. You'd want to head down to Mexico and get that done down there.
The coaches that have popouts,are they prone to not working where the selonoids click or just usually a connection problem or low voltage? Do they have a manual crank also?
I think you are talking 'slideouts'? 'Popouts' are manually extended and have springs to help operate them (like those Colman folding campers), slides are electrically or hydraulically operated.
Anyway, slides need the batteries to be in good condition to operate. Clicking solenoids usually indicate a nearly dead battery. Most Class A RVs with slides do have a procedure for extending or retracting the slides for repair or other reasons but it's fairly involved because slides are usually very heavy. At least living room slides are. Retraction when the system is dead does require a crank type tool...my '02 Winnebago comes with one...but I hope to never have to use it. Only way to extend it without the power assist would require crawling under the RV with some big tools.
