Being a Nitro Offroad Nut for 8 years now, the 2 most durable trucks i've seen, and own, are the RC10GT and the Traxxas Nitro Rustler.
With the GT, you get a truck thats good for backyard bashing, and has everything you need to be competitive at any dirt track. The Nitro Rustler is a great basher, but requires a fair amount of upgrades to be competitive against GT's, Losi's, and Kyosho Ultima St's. Add some Big Bore shocks and a Ball Diff, and the N-Rustler becomes a very easy to drive and competitive race truck.
Both of these trucks have a huge aftermarket parts following, and just about every hobby shop stocks tons of parts for them.
I'm sure you'd be more then happy with either truck, Good Luck, and Welcome back to the RC world!!
