Oh..... I like the idea on the thick grease in the differential. I have not had any trouble with the tracks slipping thusfar. I have lost some screws that are very flimsy. I drive 525 miles to Danville from northern NJ so mine are subjected to quite a bit of vibration. There are only a few very small screws holding on the boggies. I have had to tighten them frequently and even added lock-tight. How about that long over hand from bumper with the winch. I found that to be alsmost as bad as those rigid rear mud flaps. That winch bumper would dig into modest hills and stop you like an arresting cable on a aircraft carrier. The lights and LED maching guns with sound are a nice touch. The only thing they left out was an engine noise while driving and an assortment of radio channels.
