Question Roof Top AC Unit - I could use your brains!

Hello to all the Transit DIYers that have inspired me to take the plunge. Quitting my job, selling everything, moving into the van and hitting the road early next year. Just a bit of adventure before I get too old to enjoy it.


I am going to install a Dometic Heat Pump / AC Unit for when I am driveway camping or have access to some 110 voltage. The current plans for the roof top real estate will look like this.





I am putting the AC unit in the back in order to utilize the 2 internal cross beams for support. I have also purchased and received the Roof Adapters from Hein at Impact3D.


The hole will need to be the standard 14x14 cutout and I am going to place it here.



I am simply asking for guidance and knowledge from those that have done similar. A roof vent is one thing. A 72 pound AC unit is another.


Ill be creating some additional cross pieces and securing them with RivNuts for more bracing. I would rather it be overbuilt.


I have found it is very difficult to locate pics of other AC installs on the Transit. If you have any links or pics, please let me know.


Much sincere thanks in advance for the insight and knowledge.


Johnny

What length is your transit, what ac unit? I have thought about installing a ac also, but I did not find many pictures either. Look at yahoo pictures for caring van in Oklahoma city, there is a pic of a med length van with ac. It looks like its located in center of van. Also, check at where the ac unit hole is located, I think it is located in the front section of ac and this will not work on rear of med van because it will overhang past rear of van.(I think ) Post pictures and install...I still want an rooftop ac. Im just not sure about location. Im going to install my maxxfan in the rear and go from there.

Great questions, Stevigee.


I have the LWB High Roof. Looks like this.





The Dometic unit I went with is the B59196.XX1J0 in Black. It looks like this.





The line drawing at the top is to scale. The two factory crossbeams at the back are going to have more weight capacity due to their close location to each other. My Fantastic Fan will be located closer to the front between my two solar panels.

Many thanks for the search link. I did quite a few searches but 120 was not one.


However, even after looking through those search returns, I still don't see any others that are mounting a similar unit in the area on the roof.

yeah heat pumps have been talked about here but i do not think anyone has done one, i think i saw one or two 12volt dc roof mount air conditioners running on lithium batteries here, but everything else has been coleman roof mounts, window units and portable ones. you may be the first? for what it is worth: i have installed many coleman roof mounts in the past, they are easier to install then that fantastcfan vent, just 4 hold down bolts and maybe a condensation drain line!

Nope

120v air conditioning

New mini heat pump in my Transit

I went with the low profile Dometic on my HR- didn't want that tall one they sell on such a high vehicle..

I had the Coleman Mach professionally installed before I put the ceiling in, so that the installer could decide the best location. You can see where they chose to place it. Fan went in afterwards. Note: this is only an AC unit, not a heat pump. And it weighted over 150 pounds. We haven't tried any really cold camping yet but an electric ceramic heater, heavy curtains an an electric blanket have kept us warm enough when it gets chilly at night. (Van is currently stripped down again in anticipation of permanent build-out.)

One piece of advice I was given regarding a roof ac is to put it as far away from your bed as possible as it's noisy. I wouldn't know. I'm considering a mini split myself, and staying off the roof with an a/c (HR van).

the second link is not a true heat pump, it is just an air conditioner with a water cooled condenser coil
