Sounds to me like a lot of your problems with the wall jack are self induced....... A pinned adjustable elbow fastened to the stove so it can't pull out, with a steeply angled pipe, does away with the funky, draft-killing horizontal run and worries about pipe 'coming out'. But having a few sheet metal screws and a screwdriver, and maybe a chunk of tie wire on hand, is beyond many.It has a sidewall stove jack
It's such a pain in the ass with the stove pipes having to do 90 degrees to get out and then to go up. The weight of the pipes makes is susceptible to the pipe coming out of the stove or getting knocked off by wind. It's also a LOT harder to draft correctly and is a finicky bit%h.
Under optimal conditions, there's not much issue with sidewall stove jack, but if you're camping more than 2-3 days, there's going be either a storm, wind, rain, snow, etc, that's going to screw with your stove and pipes.
But then again, I've probably spent more time in a wall tent than anybody here, and kinda know what works by now....
