Since I too am doing all the necessary research on a concession trailer build, I have been reading all of the related threads and taking notes. Does anyone care to post negative/positive results with their type of exhaust fan setups (vertical/horizontal with/without makeup air...etc)?

    To start with you need to keep in mind the overall height of your truck or trailer. And not just for highway use but for city driving as well. Most cities don't trim tree branches that hang out over streets and instead depend on semi trucks to clear low hanging branches. So semi drivers drive in the center lane when possible which means the curb lanes have lots of tree branches that will beat the heck out of your above exhaust fan housing and when it gets dented it loses some of it's designed swirl exhaust ability.

        Keep in mind what ever system/equipment installed, it will need cleaning to remove buildup of grease from the inside of duct & fan. Slope any duct work to drain into a grease collection can or to the outside.    ... Yes the ducts are very short in a truck ... usually.   So make any access needed easy so cleaning will not be a 'dreaded chore'.

          Someone on here not to long ago built a truck and we talked about where to get the fans like the food trucks used.I forget where he said. but search this forum and you'll find it.

            Thanks edwmax, ease of upkeep is paramount.

              This is the system I am using for my exhaust at the back of my rig. The metal fan motor mounts have since been painted, and the fans wired up with their switches at the front of the rig.
              The next step is the custom hood, which is being fabricated locally. These fans (12v) move plenty of air and I imagine I will only need them on low. I'll have a 3' propane griddle next to a propane steam table at the back.
               
              I too was not interested in a vertical exhaust setup. Mostly because the fan systems are all AC power and I wanted 12v power for everything. But also because of the aesthetic of a huge fan on top of a moving truck. I did some research and saw some wall mount exhausts and that gave me the confidence to proceed with this custom job.

                Are either of the fans adjacent to the cooking area/hood?

                  I opted to go with fans on the side of the truck vs the top as well.  I originally bought an amazing 14" fan (3 speeds up to 2100 cfm I think) but it was just a little too big so I had to end up going with 3 smaller 10" fans.  Still wish I could have found a way to go with the smaller as it is still more cfm than the three combined but se la vie....

                    I have a friend that runs a meatball truck out of Tampa. It is an older self built including his home made side vent exhaust. Right now he is grandfathered in with the hood he has but they are all over him to change out to a roof mount. Their reasoning is that a side mount pushes the grease out while the roof mount pulls it out and is more efficient and there for cleaner and less likely to accumulate grease.

                      Valid point but not a law, yet  As long as its the right motors and they're cleaned well and often then they're just as good, if not better, than their roof top counterparts.  I would never go the roof mount...just my .02 pesos...

                        I am not sure if this thread is still being followed but this is what I have been installing.
                         
                        Low profile with a 16" total height ,1600 cfm and assembled with easily available parts.
                        I reinforce the curved front to deflect the tree branches.
                         
                        The problem with roof mounted downdraft is the grease is deposited on the roof long term,side draft would need to be strong enough to "blow" the grease laden air away from the truck.
                         
                        Well, I put a pic in but because I am new, no post. any other options?
