Still waiting on the wheels but mostly done. I decided to lengthen my 6.5x12 ft. trailer to 16 ft. to accommodate two ztr's with bagger plus some extra for whatever comes up. Since the trailer has been long paid for and in great shape it seemed more cost efficient to extend it instead of trying to sell and then buy new or used. Final cost $655 total in materials and labor. The decision was made to make the extension in the middle area instead of messing with the tongue or gate area since the second axle was being added and configured to proper measurements for a 16 footer. The new axle is accommodated with a brake. Should be plenty. Since the trailer is more on the lighter side, two cross members were added to the floor and sides, plus a 3ft.x2ft. sheet of steel was added to the sides over the axles to help stiffen the area with the most stress. Since I was concerned with keeping costs down I did not go with a whole new deck. Looks a little janky but who cares. It really doesn't matter, the wood was still in really good shape and it saved me over $150. My truck was already set up with a brake controller and works great. Lights needed to be rewired anyway. So it can be done affordably and is worth the work and experience. I did get some deals on materials. FYI. So total investment on 16 ft. trailer ends up being $1650 for 13 years of use and hopefully 13 more. Seems good to me.
