ya dual cases make it easy to navigate obstacle without worry of stalling, makes "one luggin it" happen, and is the pimp deluxeness man! I've had my rear welded on all the trucks i've run and only real downside (granted its welded up correctly) is you burn up your tires, make em all racing slick style faster then would be with an actual locker. Most lockers like the Lockrite and Aussie allow one wheel to spin faster around turns so it doesnt create stress or eat up tires but still remains locked. I've been looking into the aussie locker for sometime now and it seems like a great product and they have tons of info on their website. I'd suggest buying that thing up man, always good to get parts already on the truck, but replace that rear end (easily done) when you get a chance since it'll be your DD. I'd also recommend the advice of others on here for realizing your own skill level, possibly building a truck up to learn about how things work and react. And this way you'd build skill driving and not rollover on something stupid your first time which seems to happen to those of us who are too GUNGHOE at times, and gain alot of knowledge! My .02. But welcome to the kick a$$ world of Toyota and wheeling bud!
