Most RVs use the same 12V house system, so the same batteries work across them. The differences are in charging:
• Travel trailers and fifth wheels: charging from the tow vehicle is limited (see question 42).
• Motorhomes: the engine’s alternator can charge your house batteries, but only if its output tops out at 14.6V or below.
• Camper vans: space is tight, so the smaller size and lighter weight of lithium matter most.
