There's a gasket (black, rubber, even marked with an "X") under the driver side rear bumper.

Just run a short 14Gauge extension cord through this (or really just a pigtail with only the male end hanging out a few inches) and pull it up into the interior via the rear driver side pillar.

Shore power!

Thanks Vanguy, if plan A fails your idea is plan B! I have this plug on the way

I will see if I can trim it to fit the reflector recess and attach the reflector to the cap.

Of all the Promaster hacks and tips and standard procedures, I'm shocked that simply using the built in rubber access hasket/hoile hasn't become the standard way for conversions to access shore power.

No drilling, no new hole, no visible entry, only requires a short extension cord or short section of 3 THHN 12GA wires, and is situated to the rear of the vehicle so if you forget and drive away, it unplugs itself.

One thing you learn here is that nothing is standard. 😉

I agree with your premise, though.

Passenger side as well. My factory hitch wiring goes thru the driver’s side rubber gasket;

I agree that an extension cord would definitely be the easiest, if the reflector access doesn't work that is the way I will go. I used the access point on the left side for my fresh water overflow.

The more I look the more I find pre-existing holes in the ProMaster. I removed the outside trim below the drivers B pillar and found a 2x2 inch square hole that has been covered with a rubberized membrane - sort of butyl rubber and duct tape combo.... Anyway it easily fits my Wellluck shore plug without any drilling required..

Can you provide us with a photo?

Best we don’t use the PM platform for DIY Submarines 😜

I put both the shore power plug and the Cable TV plug under the rear bumper. When either is connected and laying on the ground it's hard to tell they're attached. And your shore power plug is smaller than mine (30 amp). So it would be stealthier.

Came close to doing it but ended up installing the socket in the black cladding below the gas door. Made an ABS plastic spacer with VHB tape on both sides to fill in the space under the cladding which makes it stable. With 700 watts of solar, I only use this when camping in the winter if there are a lot of tall trees.

[VanGuy]

Just look in front of the driver side rear bumper for a black rubber rectangle with a gasket/X hole. It faces rear.

@Jenmcd - don’t you have a PM City? I don’t think that applies to your van.

RV8Rs New Build - TETRIS

I'm surprised you're not considering an Isotherm or heat transfer type system...I'd be interested to hear your reasoning. I have considered Isotherm & the Johnson Pump heat exchangers also - quite a bit actually. Fear is the reason 🙀. Best of all it is unsubstantiated Fear (or at best it is...

This is what I have done in my 2018 & 2021 van builds.

This is more complex than the suggestions above & also thru the driver’s side wall. I thought you were leaning towards a simpler & less expensive product?

Getting 120V inside

 

[phil]

on a budget?
I got one of these IIRC $2, run the cord down the d-pillar and out the trailer wiring grommet.

 

[Zoomyn]

Whatever as-built comes make sure its strong enough & designed as straight line pull apart so when van is driven away still connected it's not pulling out house wiring when the cord gets snagged a mile or so down the road...
