For the door moulding I used is Metro Moulded IS-MW00100 Door Seal, I ordered one box off of Amazon $35, fits perfect, I think I had 3 inches left over to trim off. Bought a new Deep Cycle Marine battery
with 105 amp hours at Walmart for $75. I will be buying a solar
trickle charger to keep the battery
charged. and a 12 volt battery switch to put inside the camper to turn the battery on and off to save power. Box for the battery was also a Walmart buy for $7.50 The regulator for the propane
had to be replaced so I bought one that had 3 feet of hose with it and replaced the entire connecting line, teflon taped the connectors and bolted the tank down. 12 volt system is running perfectly now.
