I went thru the same search thing your doing now Farmboy a couple years ago. Bottom line from what I found was either you pay somebody to make you a custom cover that fits well, or you go right back to Tracker to get it.
I have a 2002 bass tracker 175xt. I gave Tracker my boat specs and they sent me the cover made for the boat. You can buy them for cheaper, but they will not fit well. I have made several trips from MI down to AR/MS pulling my boat and have not had any issues yet with wear on the cover. I travel with both the bow and stern seats in position (daughter made some seat covers to keep the corners of the seats from wearing plus I reenforced those areas), plus a have a custom storage rack for my rods. I have to uncouple my trolling motor and set it back on the bow deck for the cover to fit, but it works well.
Hope this all helps.
