Recommendations RV Repair electrical/inverter NC

I ran my DP Winnebago for several years with the inverter sitting at home. I made a jumper from the hot side of the chassis batteries to the hot side of the deep cycle house batteries and they would charge while going down the road. If they became depleted while sitting I had a charger that I hooked up to replenish them......worked for me as I was to lazy to reinstall the inverter after having it repaired the 2nd time
