If I have 2-12v batteries wired the way it is pictured on this site to have 24v output and connect it to my 12 v campers wiring system will that 24v output system fry the wiring and 12 v equipment in the rv?

Yes, wiring two 12 volt batteries in series to get 24 volts could be damaging to 12 volt accessories. Generally speaking you will want to wire your two 12 volt batteries in parallel, and wiring batteries in series is often associated with 6 volt batteries in order to produce 12 volts. For wire you can use Ring Terminals # DW05741-1 and 10 gauge # 10-1-1, which is sold by the foot, to connect your batteries.
