Spoke to the dealer today. A third function, installed would run about $900 and isn't a standard option for the MX5100. Said it could still be done, but still recommended that I wait until the
grapple becomes a reality, then run lines from the rear remote to the front... Maybe $300... it "won't be as pretty, but it will save a lot and most people don't end up using them too much." If I were using it regularly, he thought it would be a good idea.
I'm sure there are other opinions here on what would be best for my situtation. However, I have a lot of respect for a dealer that will give advice that earns him less money.
Thanks to all for their advice. A
grapple is in the future, for sure!
