Just space your wheels out in the back so it will be as stable as possible when your arm is streached out. and keep the joints greased it seems like mine always stop taking grease and i have to take the zerks out and clean them. nothing as bad as a boom arm with a bunch of sloppy joints from worn out bushings. If it useing machanical linkage controlers make sure you have them located so there is plenty of slack so that when you move the three point hitch down wont pull the cable and break them. that one cost me 300.00 in repairs.
