I would consider what is "common" in your parts.
In our parts a L3901 is expected to have a 3rd function on the front and at least a couple of rear hyd. options.
W/O people would wonder why, it would be a harder sell, etc.... Getting it from dealer at time of sale is like 1/2 price vs doing it after the fact if your mindset changes. I think you get back the 1/2 price costs and more vs the new owner doing if needed.
But if its going to be your forever machine and your sure no need then save the cash.
congrats!!
