This can be a sensitive topic since most all of us do love our ride to the THs, but the "final word" in my semi-expert 4x4 opinion

is: Matt Gilbert has the
ideal TH ride in his Toyota- Tacoma Prerunner 4x2 with back axle locker!
If I could do it without taking a major loss (which I can't & won't), I would part with my
very $highly modified$ '92 Jeep Wrangler-YJ and do exactly what Matt has done. The Tacoma Prerunner has excellent clearance with stock P265x16x10'' tires
and a very well designed drive train with a cleanly designed undercarriage(very little hanging down to get in the way of rocks, ruts,etc..)
and buying it with or installing an aftermarket "on/off" locker in the back axle adds a whole new level of security for those occasional AZ 4x4 TH back roads
and buying a 4x2 will give you better gas mileage
and less insurance costs than owning a 4x4
and now you can buy a sweet four door version if you need more passenger or inside cargo space!
IF you just can't go with a truck, then my second choice would be the Nissan Xterra full 4x4 version. Also an excellent choice but my second choice..
