I can recomend a Jammin truggy... it's a proven, tough truck.
There are some interesting options like maybe a XTM Mammoth... it's only $350 RTR so you can part out a bunch of stuff and pay for at least half of it. It's not as much a true "truggy" as the ones from Jammin, Kyosho, TTR,etc... but it will work just the same. I think it's a little bigger than most truggies, good or bad.

You will need some super thick stuff in the center diff to get easy wheelies.
For a Neu, I like the 1515 2.5D I have in my truggy. It's fast enough on 4s, but in the future I have the option of bumping the voltage up a bit, and dropping the gearing a bit.
