I would try U-Ship. I've used it twice in the past to ship a big old vintage reel mower across the country and a 1980s KTM dirt bike most recently. Just make sure the shipper you go with has positive feedback. :thumbs:
I have used Uship many times. I have had great experiences, and bad ones. Another collector here even had to take legal action with a carrier once. Fastenal is a great, no BS way to ship stuff, but requires seller cooperation. Uship provides carrier feedback, tracking etc. I would always prefer to have someone pickup and provide me with real time updates, as a few of the Uship carriers I have used do, but Fastenal is substantially cheaper and extremely convenient for me.
My recommendation is to find a Uship carrier who is somewhat local to you, or passses through your area regularly. For several shipments, I dealt with a carrier who towed new RV's out to the East coast from WI, passing by me, in southern MI. He was always on the hunt for something to bring back west with him, and I filled his truck several times. Once I had a great transaction with him under my belt, I simply held onto his biz card and would call, text or email him inquiring about his availability and rates. I also passed his info around to fellow collectors in MI, IN and WI, and I think it helped build some credibility for both of us.
I have shipped mower decks, and tires UPS with good results, but large lightweight, and Small items go through the mail, shipped a Farmall c grill to PA once and despite being large, the fact that it was light meant it was cheaper to send it first class mail than UPS, an idea of what you are shipping would make it easier to give you a better idea of what is the best option.
