Amazon has one for cheap that looks like it would fit ok.
BroilPro Accessories H4930.. Don’t know a thing about the company or this product.
Classic Accessories has a line of smoker covers that almost would fit and I have a couple of the Ravena products that are good quality. I was hoping to find one for them to match the rest of my outdoor cookware. But nope. Doesn’t look like it would fit.
On the limo, the measurement of depth is 26 which is mostly accurate. The Tru Tell thermometer sticks out a bit further. I measured mine at 28”. I think the Broilpro having extra width will allow the thermometer to pop out without problem.
