Great info there JP.....dum dum...who'd a thunk it? What's nice about that as well is that if you ever have to take them out, re-sealing will be easier without having to scrape and clean the sealing surfaces so much. I'll pick up a couple of tubes of marine grease.....
Once I get the rolling stock together, my next round of questions will start.....but all of the info has been very helpful, so thanks everybody. It is kinda hard building something when you have very little experience driving it, or just knowing the best way to do something so that you eliminate problems before they happen. I absolutely hate forced marches...if I'm walking by choice that's one thing..but when you are out hunting, it's either cold or hot, either way I will have waders on...so hopefully everything will work as well as I hope it will.
