The seat belt extenders come in different lengths. I got one for my son so he can put himself in and out of his carseat by himself. It move the buckle up about 6 inches so he can reach it while in his seat and I dont have to crawl into the back of the truck to do/undo the buckle for him.
I dont like the way the seatbelts come out of the seat on the dodge trucks, (and I use the word "truck" loosely

) My buddy has seat covers he puts on during hunting season so the seats dont get dirty, but with the seat covers you cant use the seatbelt.

I suppose somebody makes an overpriced seat cover that fits the dodge vehicles but he didnt find them. Poor design IMHO.
