1200watt PwrInv and keep my string lights on

Plug them into a plug that isn’t powered by the APU.
You should have plugs that are powered only by the inverter.
Not really sure why you want those lights on while driving. The reflection in the windshield would be awful.

 

Plugs that fit cigarette lighters are usually in the drivers area or bunk area. Can use those for extra lights.

Can also go to an RV dealership and get that taken care of.

 

You should not be allowed to have a lighted cab.

 

Why not ? It’s cool, makes one look like a Super Trucker…….

 

Like a super fool. While you're park yes it's kool nice to look at. But once you start rolling you should be all business. Besides I wouldn't want any unnecessary attention. Be smart driver.

 

There are 12V string lights that are much easier to deal with, use less energy because you’re not inverting power to run them, and make more sense for the application.

In my previous Volvo, I found a string of self-adhesive lights and mounted them across the underside of the dash. This provided me with plenty of ambient lighting to see all the floor, up front.

 

You must be “new” on here with a first post. You didn’t understand my comical comment. The emoji’s speak for themselves in it.
