What is your intent... to maintain the batteries fully charged while in storage?
Disconnect the battery from the trailer in storage, buy a PWM charge controller on ebay for $10, and a 40 w panel for storage.
40w 12v panel
Buy a bigger panel if you want to recharge your batteries while camping. Calculate your daily amp usage first, then buy panels. 1 to 1.5 watts per amp you use per day.
Extensive selections of 12v panels.
I have two standard 12v deep cycle batteries but I don't have their specs right now. I would be using this system to charge my batteries while camping. My Honda eu2000i would be used for the microwave etc. I like the kits because they come setup already.

You'll have no idea what or how much to buy, nor will those trying to help you, until you perform your homework above. Do a search on BFL13 he has a spread worksheet to help you figure out your estimated amp usage, per day.
If you dry camp, a lot, the first change I would make is converting all incandescent light bulbs to LED's to save current draw and amps needed to be recharged. It's cost effective in the sense that it allows you to buy less amps /watts in solar panels to recharge on a daily basis, less % loss on the batteries.
