We are working on fabricating a couple bars that will lock the racks into place and not allow them swing. As for the vent thru the roof is where our problem is still lurking. We aren't going to be going far. 15-20 miles max. But the wind causing a vacuum and possibly putting the fire out thus creating temp changes is our next task. Once we get that figured out we will post up here. Also on our list is a air scrubber for the smoker vent to be able to pull the trailer indoors so that we can sell at large indoor events like the Farm Machinery show.
