 PLEASE INSPECT THE CABLE  GOING FROM THE BATTERY TO THE INVERTER!  Many of us gurus had to replace ours.

Here is a picture of the cabling I removed:  

That is what I would expect of WELDING cable - the insulation isn't suited for the automotive environment. It may be tough & abrasion resistant, but it isn't rated for oil & fuel exposure. It is also expected that welding cable will be fully exposed - that way failing insulation can be readily observed.
I was surprised to see that Newell used welding cable when tinned boat cable with better insulation is only a little more . . .

In my opinion, Marine boat cable is a much better fit for our coaches.
