It's easy for us to spend your money, we don't have to pay it back, but here goes, these are my picks.
Get all the options that you will need when you get it, like a third fuction for the loader, remotes for the rear, and load the tires, Rimguard (beet juice) is the best.
Also for loader use your going to want a ballast box or a heavy implement to offset the weight of the loader and load.
On the bigger L's and MX's and M's I would also suggest rear wheel weights, the more the better!
