Connecting a Portable Diesel Heater to a Truck Bed with Inside Ducting to Tent

Previous posts show different ways to connect the heater vent to the camper. This is how I connected to my RAM pickup. Growing up on boats in South FL I decided to use a Marine Deck Cowl Vent.
They are available in 3" and 4" diameters.
Check out the following link and photos.

One more issue I ran across. My solar system is a Ecoflow Delta2. The 12vdc output is 10 amps. The HCALORY 12V Portable Diesel Air Heater spikes over 10 amps when the glow plug and blower goes to high speed at start-up. This tripped the 12 vdc overload.

If you do not have a built in solar system.
My solution is connecting the heater to the vehicle main battery. Then since the Ecoflow has 110vac then connect a 2 amp trickle charger to the main battery to keep it charging off the 110vac from the Delta2. The trickle charge draws less then a half watt.
Plus on a cold winter night you can connect the trickle charge to your house 110vac and keep your battery charged and ready for the morning.

FYI: I do not use the vent scoop but took a photo for kicks.

Ducting Inside The Camper:

The following photos are how I ran the duct hoses for my external Diesel Heater.
The parts I used will be after the photos.
I used an adjustable “Y” heater valve so I can direct the heat to the bottom truck bed or to the upper tent or to both.



I used the 3 inch “Y” from Amazon I listed before.
The rest came from Lowe’s. Here is the link one more time.

Fitting going through the deck is shop shop vac coupling from Amazon. Make the hole through the deck slightly smaller ( I mean slightly smaller) and wedge the coupling in the hole.

To attach the vent hose to the bottom of the deck I took apart the vent fitting that came with the heater and screwed it over the coupling the was wedged through the decking.

I really like the idea. What does it look like on the backside after you installed it .

Are you asking about the inside duct work?

I’m still working on it.
I already cut a hole in the nonremovable deck on the opposite side and have a PVC coupling going through the deck with a removable 90° elbow on the top to direct the airflow. Removable 90° to allow the top to close. I am also thinking about put a tee in the hose to allow airflow in the bed of the truck and the tent at the same time. I will make it that the tee directs the airflow. I just want to make sure there is no back pressure (restriction) to limit the airflow through the heater to overheat the heater. I still need to test it when it gets cold.

Pre warning. I’ve already been told multiple times this is not an ideal way to mount/install/run a diesel heater because of numerous violations of the exhaust.

With the pre-chastise out of the way.

I just finished my diesel heater install inside my GFC as a way of making winter camping in alaska possible and more tolerable. After four nights of testing I can confirm it works wonderfully and I will likely upgrade the heater when this one dies or sometime over next summer with a better heater case.

I run two carbon monoxide detectors. One in the truck bed where the dog sleeps. One in the tent where I sleep.

I vent two panels (passenger front and driver rear) using the latches and then crack a vent by the hinge on the front of the tent to allow cross-breeze.

Since I was doing the work and I am not a professional I opted to keep the heater and fire away from the vehicle. Being in a tent on top I didn’t want to get roasted.

How far I keep the heater away from the vehicle will be determined.

If you have the full bed installed, like 2 people are sleeping in the tent, does the heat rise up into the tent? Or do you have some sort of a vent from the truck bed to the bed bed?

Super cool setup!

This is the “Y” fitting instead of a tee.
