Cost For Solar Install Please

I did panel installs involving 4 90 watt panels mounted in the rear and batteries located in the front cargo area. The charging cable had to pass down into the bedroom behind the rear wall panel. Inverter install was next to the batteries. I had to run a 6 gauge cable forward under the rig in one frame channel and 8/3 wire forward in the other frame channel. Using liquitite armored tubing. So commenting on this without having your specifics is like ------- upwind. I can comment using a yacht bung seal and passing the cable down insulation then through the deck took the better part of 5 hours. R&R of the wood panel was not something to be rushed. Neither was actual mounting of the panel retaining hardware. When doing work by bid it is overwhelmingly tempting to rush things when install time is longer than predicted. I eliminated this by insisting the rig owner help. The last install was done on an Arctic Fox. The owner was a pilot for Delta. He said afterward "I still can't believe how much work was involved". I hope your install is easier.
