man the jump from a 4runner to an LX is nuts (the below numbers are for 2015 T4R, LX, LC)
your looking at 39k (TE) / 43k (LE) to a 85k vehicle. another option is the land cruiser.
granted the LX has better interior appointments, but if you decide to take it offroad the LC and/or the 4runner is probably better in a nutshell.
LX = prem fuel
LC = reg fuel
outside of the following everthing is the same between a LX and LC (1st # = LX, 2nd # = LC) :
Maximum Trailering Capacity (lbs) 7000 8200
Dead Weight Hitch - Max Tongue Wt. (lbs) 700 820
Wt Distributing Hitch - Max Tongue Wt. (lbs) 1050 1230
Dead Weight Hitch - Max Trailer Wt. (lbs) 7000 8200
Wt Distributing Hitch - Max Trailer Wt. (lbs) 7000 8200
