I have a 2014 35' Laredo with 2 roof A/C. To run both A/C I had to have 50 amp service. A lot of FL state parks only have 30 amp and a separate 20 amp GFI.
I put 2@ 20 amp individual wall (roof) plug in (female), one wired to the RV electrical system, the other a separate 10/3 new circuit that terminates at the road side storage box access. Buy or make a 10/3 extension cord to go from the storage box access to the site power pedestal.
Open the bottom shroud frame of the A/C unit. Put in a 2' length of 10/3 to the A/C unit electrical system with a male plug.
Have 50 amp pedestal, plug A/C 2' plugin into the RV electrical plug in the roof.
Have only 30 amp and a 20 amp GFI on the pedestal, plug A/C 2' plugin into the separate new circuit in the ceiling and of course from the street side storage access to the pedestal 20 amp GFI.
Now you can camp in older parks and run both A/C's without any issue and not a "cheater" plugged into the adjacent site electrical system.
Task:
1. disconnect RV electrical from A/C shroud
2. create 2' 10/3 extension cord wired into roof A/C and terminated to a 20 amp male T plug
remove existing roof A/C electrical box
3. install new 2 gang electrical box. I added side wood blocks glued to space between ceiling and roof of RV to stabilize new electrical box.
4. wire existing RV electrical to 20 amp T plug female single receptacle closest to A/C
5. extend new wire from second new 20 amp T plug female single receptacle (furthest from A/C) across ceiling to front closet, down closet to storage compartment, across to street side storage access door terminate to a 20 amp T plug male.
6. Obtain 50' 20 amp T plug (both ends) extension cord. One end (male T plug) plugs into 20 amp female T plug receptacle on pedestal, other end 20 amp T plug female plugs into the 20 amp T plug male you terminated at the street side storage box access door.
