"wanting something that can give me a descent extra recharge throughout the day to keep the batteries going for a good solid 3 days 2 nights"
Your daily use will have to be known before anyone can estimate how much solar is going to help.
Hey, also, are you seriously going to cut the doors over your the propane tanks to squeeze in two 6v jars? I've looked at the pictures of your battery holder and it would seem all that is necessary is to cut a couple of steel straps and weld in some short pieces. Is this an economy thing?
There are 60 watt panels available at Solar Blvd for $78. Add a $20 solar controller and you will have doubled your original 30 watts.
