Have an older Bounder and always wanted to be able to run both A/C's at same time. An electrician looked at my RV and has suggested I change from 30amp shore cord to a 50amp, install a two space 30amp breaker box in the basement compartment and connect L1 to existing wiring. With L2, install a second independent breaker box and move rear A/C, bathroom and bedroom outlets from existing house box to new. Now L1 will power kitchen forward (and front A/C), while L2 will power bathroom backward (and rear A/C.) He says its no different than using a 50amp to 30amp dogleg whereby your only using L1 from the 50amp plug and I'd never be able to draw more than 30amps off either L1 or L2 without blowing the 30amp breaker in the new breaker box. Also, that I won't have to upgrade any wiring since I haven't technically converted from 30amp to 50amp, rather just installing "two" 30amp services into coach with L1 powering front half and L2 powering back half. Should I have any concerns????
