I am looking to buy a new trailer. I currently use a 8'6" X 18' snowmobile trailer, which has worked very well the past few years, but I think it is time to get something heavier. Also getting tired of having to drag the ramp out from under the trailer and hooking it on the lip, so a fold-up ramp would be nice. I need something about 18-20' long due to hauling two Deere 425 AWS with cart baggers. Also, spring and fall clean-up would like to consider having a removable box in front section for clippings/leaves. Any suggestions?
