10 to 15 years ago I went several years straight with an excess of free venison. I made lots of jerky. I seasoned it with salt, sugar, pepper, salad dressing.... It was all good.
Too much salt was easy to achieve, but it was still good.
Smoking it in a smoker added a dimension to the flavor, but I decided drying it in the
oven was easier and just as good.
It wasn't juicy and tender like Jack's Links, but it was tasty and filling. The thing I decided was most important was trimming the meat properly, to eliminate any traces of tendons and most or all of the fat. The trimming of the meat was the most tedious part.
I tried recipe after recipe, the best was a mix of salt, brown sugar, and black pepper. Less is better, season to taste. Soak it in a marinade in the fridge for 12-36 hours and dry thoroughly in the oven.
The smoker wasn't worth it, in my opinion. It was added hassle and took longer than the oven, the flavor it gave was not good
enough in comparison to beat the 1/2 or 1/3 as long a drying time in a 130+ degree oven.
I'd estimate a shelf life of several weeks or more in the pantry, keeping it dry is important. Months or years in the freezer. Mine never lasted that long before it was eaten.
I made a lot of jerky, making up a new recipe for each batch. Some of it was excellent, some of it wasn't as good as that other batch. But it all got ate.
I never got around to trying to reconstitute any into soup or stew. I wish I had.
