I got the Ryobi one+ as well. Works great on all the trailers. I got the One+ because I had a lot of the Ryobi stuff already for camping (18v chainsaw, fan, radio, air compressor, torch, dust buster) and they all take the same battery.
I've use the impact wrench on wheel nuts, and the bolts that hold on the points on my 14 run seeder. I was hoping to just break off the bolts but it actually got the nut off (not sure how, I didn't think there was thread on the end of the bolt

). It seems to be perfect for me as its only the odd job here and there. Like most things, for industrial applications can't go past a Makita or similar industrial brand.
Let us know what you end up with D4D and let me know how it goes.
