I mean look at their universal cover here: Universal Shroud Cover | Dusty Motors It is clearly perforated and designed to allow the electronics to breath just fine. I would definitely never use one of those solid body shell-type covers of that's what you mean.

I'm not sure if it is the additional weight of a truggy as apposed to a buggy in the rear end, but I tend to diff out a lot, even with the rear suspension raised and having a "rake" stance for the truggy. The only real solution I have found that doesn't require upgrading diff cases is to run heavier weight oil in the center diff (20k-30k roughly). This, however, tends to spoil handling quite a bit on a track and my lap times usually suffer quite a bit. I have been racing in the desert of Utah though, on very light dust and sand that is extremely slippery, and I will be living in Seattle soon so perhaps the problem will stop.

I don't doubt for even a second that either one of these truggies is anything less than extremely tough, but in my experience with my old Serpent Cobra, its a good idea to choose a vehicle that at least has aluminum options, should you need to upgrade later on. I think I have just decided to go with the ET48.3 over the XT8E, though.
