Hey Mike, I would go with a permanent install solar panel kit like the Go Power Retreat part # 34272635 which at it's peak can put out a 5.43 amp charge which would do a great job keeping your battery topped off during the week. The panel isn't huge but it is a decent size at 47-1/8" long x 21-1/2" wide which you'd need to mount on the trailer in an area that gets sunlight like maybe on the tongue but it really depends on how the trailer is setup.
