Duanet, I also teach online course at a University, so once I am on the workstation, I typically do see a lot of the messages that come across the Web for me, and if I happen to be on this site......oh well. You may want to reduce those fronts to 22, as that is what is recommended on the fronts of mine (Bridgestones). I probably will go to 14 - 20 on the rears. Yes if you plan on carrying your 4100 around with implements, then you probably should go with something that is capable of carrying 4-5000 lbs. The unit weighs ~1500 lbs by itself. My trailer has a capacity of 2900GVWR, but that means that I can only carry up to 2200 lbs in its present state. I am thinking that I may want to beef it up (double axle it or trade up). The limiting factor for me is that I need a trailer the same size, so trading up is a problem. modifying it, seems more likely. I will check with the trailer dealer and see what they can do - they do mods. I am also asking the manufacturer too.
