I use my PMC as a camper RV. As summer has approached, it has been getting too hot to sleep in there. I'm looking at a Fantastic or Maxx Air RV power vent. That requires a 14 x 14 hole! I'm not all that excited about cutting that big a hole into my new PMC. I've also found a smaller 6.25 round power vent that might work. Anybody have experiences to share regarding cargo area ventilation?

(I know that running a power vent will chew up the battery, so I plan to run it off of a Yeti solar generator and panel.)

rich,

Before finding a low profile fan, (but still 14" square vent) I was planning on putting a vent in each rear door. I bought these: (taped in place for visual look)


These have a flap to allow air out, and with a few computer cooling fans, you could probably run two off a small portable solar panel directly. If you're interested, I have 2 brand new available at a reasonable price. Depends on the color of your City too.

My plan is to make air flow units that I roll down the front windows to install.

I'm thinking of overlapping the window 4" with a sandwiched bug screen inside with holes drilled through both pieces.
I like the idea of a computer fan. I was thinking of a USB fan. Run off a portable cell phone charger battery.

I want a big fan but not this year.

Another idea: fantastic air portable amazon $70. Comes w 12' cord.
Euro camper louvered metal and screened vents. Have been using this setup for 3 summers expediting.

Curious what you finally did? I own a 2018 and I went crazy on mine. Not only cut the 14" hole for a Maxxair fan between sliding doors but also cut a 6" hole in the back under a rigid solar panel as an exhaust. I love my setup and I have tons of information about this van after messing with it for the last year and 1/2.

I was not shy about cutting and bending. I cut and bent my battery tray to squeeze in a 115AH deep cycle dual purpose battery. i cut access holes in the side panel inside and found a treasure of storage space. I welded supports on the roof for a 100 watt rigid solar panel.

The end result is a van I've used to work remote and sleep in during off-grid projects for weeks at a time so it's been worth every penny.. but I think if i were doing it again I might do a few things differently and skip some things I did.

The main reason I upgraded my battery was so i could run a 12v fridge in the back during the hot summer days and so i could run my corded power tools and 1000 watt electric kettle from a 1200 watt inverter i run under my driver side seat connected to my giant starter battery with 3' 1 gauge cables . Had I just switched to cordless tools and a portable gas stove i think I could have skipped all that.

As for the roof fan, installed a Maxxair because it's quieter than Fantastic, but those fans consume like 35 watts and I have since learned that a 9" 5v USB fan (like OPolar) only consumes 4 Watts and pushes a lot of air. Also, understanding the body of the PMC, there is an opportunity (INSTEAD) to drill 5" vent holes under the van right where the side doors start and mount some 9" USB fans inside on the wall on each side for IN and OUT and only costing only 8 watts of power for a lot of air flow. Untested but I think that would be more than enough ventilation. With a cheap 250 Watt Hour Lithium battery unit (like Jackery) you could run those for around 30 hours without charging. And you could certainly charge that battery from a cigarette lighter or a small dash or roof mounted solar.

You can find some videos on my build if you search Youtube for "Cyberpine"

Wow, I like your ideas. Keeping it simple is what I am after. I would be a little concerned about possible water migration coming up through the lower vents. Road spray seems to defy gravity.

opening is well below the floor level. It's a really deep well and the opening would be recessed up above tire mud line and it could be semi covered and placed way from drive direction. Anyways any minor water that gets in there will run back down. might also be possible to have small pop-out hatches. I have a video showing what it looks like in side that pocket on my youtube channel under "Hidden surprise storage space in a Promaster City Van side panels"

I can’t take credit for this. Somebody had a YouTube video of this. Gutter guard from H Depot. For now I’m gonna try these with an Opalar fan. If someone really wanted to be trick they could mount some USB computer fans along the shield. I was toying around with mounting a 6 inchexhaust fan to the back door where the Ram logo is. It’s about the perfect size and would be very stealth. Reinstall the Ram logo and no one would probably notice.

I find some type of extractor fan near the rear is needed in any van. Seems like an obvious and easily installed factory option which is never offered. In addition, consider a dehumidifier. If you are using this as a camper, humidity will be your primary issue. If you need to cool the van, just turn the AC on, if you have it.

I am sure the original poster has decided to do something by now. I did from etrailer a vent line vanair 6” vent fan. I run it off of my jackery explorer 240. I typically get about 12 hours of fan running before needing to charge.

I just cut some bug screen from a camping store, cut to size of each front window, installed with some magnets. Inside the van I have a clip on fan that runs on my Jackery blowing air in from the outside. It is attached with 1/8 inch wooden dowels that run the width of the van and tucked in the molding overhead. Works like a charm. I did buy the trailer vent from etrailer that allows air to passively move air but just did not want to cut into the van.. I may or may not install it at a later date. But for now what I have works great.
