In my 14, not a problem to mount a 12v outlet and the inverter to the bed side since it was steel, but my 16 is aluminum, so bi-metal corrosion and lack of strength prevent me from doing it this way.

I need some ideas to mount them to the topper without damaging the sides, or sticking out. I can mount the receptacle to the rail with short screws, but the inverter is too wide for that.

 

I would mount the inverter behind the back seat of the truck and run power out to the outlet on the bed and install a switch up front to turn it on. That is how my work truck is set up.

 

 

I need the inverter in the rear where I recharge LiPo batteries. Already have the 12V 10 Gauge run to the rear, and tapped, but would like to have the sockets and the inverter in the topper so if I need to I can remove it all as one unit. I already have an inverter in the cab, but charging Lipo's in the cab could spell disaster if one decides to not take a charge properly and go BOOOM.

I had the same setup in my 14, but with the steel bed it was simple, just bolt it to the bed wall. Can't do that in the 16, the bed wall is thin aluminum and after a while, even with aluminum screws, the metal will deform from the weight and eventually rip out.

 

Why not try one of the Box Link plates as a mount base? And how heavy is an inverter that requires only 10 ga stranded? Sounds like a 100W inverter... tiny.

I do think your caution with charging LiPos well advised...

 

IT's a 400 watt invertor, but I plan to install a double or triple outlet 12v socket so I can power an air compressor if needed when trailering.

What I think I might do is get a plate of either steel or aluminum and bend it to match the angle of the bed rail to topper, and then mount the components to that and stick it under the rail clamp. This way it is out of the way, don't need to worry about something sliding around in the bed smashing into it, and is easily accessible. I have the bed extender too, and it came out of my 14. In that truck the socket and inverter were mounted to the bed side on the left behind the extender, but on the 16, that is where the bed light is at, and not as easy to get to as it was in the 14. The bed is 2" or so shorter in height so the extender sits almost to the rail.
