Have had dual batteries on our past 2 TT and now on our 5er. Ditto the fact that there is some 12V draw all the time. Even if you rig has a built-in Battery disconnect, it might not disconnect everything. A second battery will pospone going dead, but if stored long enough both will be dead. Battery disconnect switch, avail at most Auto Parts stores. Goes right on the battery between the post and cable, will shut everything down.
