Should I sell?
I look at this a little different. I'd rather have the 340 sitting there ready. With my luck, I'd sell the 340, then take another couple of Months/years getting a 360, and all the assorted little parts to make it back to what you have right now. Along with the different seasons limiting when you can work on it, and drive it. Might be longer than that... Juse my .02 cents....
