Wall thickness for 2021 T@b 320S Boondock

DanSees

I want to add a 12v usb outlet to the exterior passenger side of my T@b 320. I am trying to find the wall thickness so I know how long of an outlet I need to order. I want to install this near the 120v outlet. I could remove this outlet just to see what the thickness is then reinstall, but I thought if anyone knows where I can find the specs or the thickness it would save me from removing this outlet & having to reseal & install it back in.

Any thoughts on replacing the existing outlet w one that has both 110 and usb ports?

Good idea @WayneW if he's always on shore power.

Probably doesn't help, but here's the wall of a 2020 320S. I didn't measure the thickness, but it may give you a rough idea until someone can give an exact number.

Yes, I just thought of the need to always have some sort of 110v power. This approach would not work while boondocking.  Good point, @AnOldUR !

I'd recommend using a PD style (Marine) outlet. Many come with a rubber cover and you can mix and match for exactly what you want. Many combinations. I'll be adding one this winter (USB and USB C) to the outside on mine with a switch on the inside and an in-line fuse. https://amzn.to/3BS8YIr
I use them on the inside also. Here's my main panel and a USB I installed by the door:

Thank you everyone. Looks 1 1/4"  I will definately add a fuse and a marine type outlet. I have found when boondocking and sitting outside it would be nice to plug in my phone or flashlight which is usb or usc . WayneW said:

I thought about this also. But would rather just install a outlet with 2 usb's and save te 120v with 2 plugs.
