by pop up camper,do you mean tent trailer or an actual pop up truck camper? i have a truck pop up ive been redoing in between trips.so far its gotten an electric water pump(no more hand pumping),new 3 way tap,i have a new power panel.inverter and battery charger to be installed soon,and i found a custom boat canvas shop to replace the vinyl and screens that are starting to tear,but they're sewn into the vinyl so why not replace it all?.i've rescreened the hard side windows and screen door myself. also have new marker and porch lites to install after the new power panel goes in.so far all the repairs have cost me less that $400.untill the vinyl anyway.
