Try and stay away from wet cell batteries if possible, They are a tad messy but more powerful than agm or similar. 110 would be big enough, you need to sit down and write a note of anything 12 v you will be using, you'll be surprised how it will add up. now you added up all watts used, divide that buy 12v. that'll leave the amps your using. then divide by 8 to get the hour rate, at this stage you may have fainted, alls good, your battery will handle this, backed by a decent 12 voly solar panel.,If you have concerns just PM. IMO it's best to let the solar run as much as possible at camp, and please remember leave your start battery for just that starting, you have the camper for anothr drycell battery for lighting duting etc, just make sure your alternator is minimum 100amps, more to it than just buying battery
