I bought the same tractor about the same time as you, so far loving it. My dealer is 30 minutes away and my purchase experience was very good and they delivered the tractor the next day. I didn't finance so never discussed insurance with them. The only implement I got from the dealer was a Dirt Dog grapple, and I purchased a Woods RD990 mower from another dealer that had it in stock. I've picked up some pretty large trees with the grapple with no issues, no idea exactly what they weighed. Still have the CK35 with backhoe and a bunch of implements, planning to purchase some larger implements for the Yanmar in the spring. I will probably get a snow plow for the front soon as I expect I'll need it before long.
My Kioti dealer tried to find me an NX6010 after the JD was repurchased but could not. It had a great lift capacity compared to most tractors. Yesterday, we went from sunny to near whiteout and back to sunny in 40 minutes. It was the first snow of the year. I did my second fill-up; the first one was at 6.8 hours, and the low fuel light was on at 21.3. It's very close to the RK55 in terms of fuel economy. I spent a couple of hours going through radios and found that Kenwood and Pioneer had receivers very close to the depth of the factory radio. I ordered the MVH-S522BS from Pioneer, so it will be interesting if it will fit. So far, I'm enjoying the tractor; all prior tractors were dual peddle hydro. But the learning curve was near zero. Its just as easy to drive.
