I inherited this 2001 palomino pop up truck bed camper. I have never owned a camper at all. A few questions to start off..

1.) When closing the roof, how can I get the canvas to fold inside?

2.) It has heat but needs air condotioner. Where do I start with a roof unit for a setup like this? It has a vent in ceiling already. Would it be easier to use a small window unit? Has all 12v wiring.

Thanks.
