I have gone to EJS the past 2 years and this year we ran Behind the Rocks (my first time, but I have done harder). I was able to walk up upchuck and going down white knuckle hill was cake for me. Only half the jeeps that tried upchuck made it and of them 2 put it on their side, I made it without so much of a chirp from the tires. I personally think that once you get to 35" tires or larger jeeps have a severe disadvantage to a fullsize thanks to wheelbase, stability, and ease of swapping in 1 tons (not to mention strength of the rest of the steering and drivetrain and V8 power). Again, Blazer Bash will be awesome and it is highly recommended, buy EJS is sweet as well and you can see tons of people do awesome stuff with some sweet buggies!
