I guess this can serve as my "roll call" as this is my first post. I'm a Northern Minnesota guy and have been smoking foods for about 18 years. I've used all types of smokers but currently run with a Camp Chef Smoke Vault, 24" and use a AMPS tray for cold smoking. I am an avid fisherman/hunter and process all my own meats and sausages. New dad to an awesome 9 month old boy and future smoker!
As to the problem at hand, as mentioned I have the SV 24 and have used it pretty extensively for about 5 years now. Here's what I've learned, and I hope some or most of this can help with your issue with your 32.
For smoking at higher temps, say 175 and up, I have no issues getting and maintaining a pretty consistent heat. For me it seems my temp gauge actually is pretty accurate, but as with most smokers you will get "hot spots" (back right for me). I have also found that in order to get chips or even pellets to actually smoke in the smoke tray, I have to hit about 170 degrees. Once they get smoking, they then create more heat, and your temp starts climbing into the 180 plus range... This is bad news if you want to smoke things like sausages, etc., where you want and need lower temps.
My solution was to get an Amazing Pellet Smoker (tray version). Because it is lit and will smoke independently, I don't need to crank my heat any higher to get the pellets to smoke. I then put my burner just a shade above its lowest setting (very lowest setting and it seems to go out with any wind gust) and that gets me to right about 165-170. Still a bit warm. I then crack the door and engage the handle so the latch it kind of stuck on the door frame, if that makes sense. This keeps the door from swinging open or closed and keeps about a 1" crack in the smoker. The result is getting smoke from the AMPS while getting about 150-155 degrees from the heat source (or even cooler temps if it's cold out--a regular occurrence in Minnesota, as you can imagine). This has allowed me to get great results from a propane smoker that you'd usually need an electric smoker for.
