It's a tiny flame and probably alright in the average draughty van but I wouldn't do it.

I put one that I bought off Amazon into my Daughters build, the exhaust I made up from diesel heater exhaust and fitted dometic fridge vents and it's working beautifully. These cheap Chinese fridges have the same exhaust as the more well known big brands but are a lot lower down due to the physical size of the fridge, so you either elevate the fridge or lengthen the exhaust as I did. Phil, simples.
P.s.
So long as the fridge is in a sealed off compartment with an exhaust that emits to the atmosphere, with vents top and bottom of the compartment there should be no danger of monoxide fumes entering the living space. If the flame is burning correctly there should not be any monoxide in any case, but correctly fitting the fridge and exhaust would prevent any monoxide from entering.
I fitted one from Ebay in my sister in laws van and that was 3 years ago, it's still doing sterling work and without fault.

Be aware that an exhaust that long could cause problems with the heater exchanger, in so much as if the heat by the exchanger is too much the fridge might be so efficient that it becomes a freezer more than a fridge, it's not the air circulation around the fins I'm talking about it's the exchange of heat to refrigerant at the burner end, I had to remove the .metal spiral plate on my daughters to let the heat disperse more easily up the exhaust because the exhaust was about 30cm longer than it should have been. Don't mix the two heat settings a) The heat that is cooled by the vents top and bottom and b) The heat that is generated in the exhaust at the burner. Phil.
P.s. Though I have in the past seen some pretty long exhausts on commercial builds at motorhome shows but unfortunately you can't find out much about the construction as inevitably the chaps on site are basically sales men and are not involved in building them.

Usually the commercial exhaust that you can purchase from the likes of Dometic, increase the exhaust length by not much more than about 15cm from the top of the fridge exhaust to where it would vent to the atmosphere. Phil.

Evening Farang,
To be honest if it's only just above the top fridge vents it wouldn't need throttling as it would only be an extra few cm in any case. One of the most important add ons with any fridge is a fan system to give a boost to the cooling air driven past the rear of the fridge. I've got two computer fans mounted behind the top fridge vent driven by the spare pump supply of my 12volt sargent ec328 consumer unit, and where loads of people were complaining the their fridges were not coping over this hot weather, our fridge has been keeping our ice cream frozen, folks couldn't believe that we were able to store ice lollies, so fans moving cooling air up through the fridge compartment really does make a difference.
But as I was suggesting the best way would be to vent these small fridges in a conventional way with Dometic style vents with the fridge raised or lowered to enable missing bodywork main supports etc. Phil

Only just noticed this post, no ideally the fridge exhaust should always be vented to outside. In theory if the fridge cabinet is sealed totally from the living space and vented top and bottom then the fridge exhaust could be allowed to directly empty into the cabinet space though in practice this would be very dangerous and could allow carbon monoxide fumes into the living space if the cabinet was not completely sealed. I personally would not go down that root.
If your talking of putting vents in the side of the van top and bottom of the fridge cabinet what is the reason you can not vent the fridge exhaust through the side aswell?
Why must you vent the exhaust through the roof. Phil
