RV Repair: Dave, how would I hook up..., camper trailer, luck dave

Question
Dave, how would I hook up 2 batteries to extend battery life for my camper trailer, thanks, Rick

Answer
Try this. It should do the trick:
First, connect the batteries together by attaching the POSITIVE battery post of the first battery to the POSITIVE post of the second battery. Similarly, attach the NEGATIVE to NEGATIVE. Remember that this hook-up will add the Amp-hrs capacity of the two batteries. Example: Two 12 Volt 30 Amp-hrs batteries in parallel will give a total 60 Amp-hrs at 12 Volt.
Good luck,
Dave
