01' Aero, CU...
Get yourself a decent MTB (and some pads), a longboard (with wheels), and park the 40 except for Friday and Saturday nights (and some Thursdays and Sundays), and weekend trips. BTW with roommates you can rent in BLDR for 350-500/mo off campus, if you live somewhere like the Hill or similar you won't need to drive to class, just point the board downhill...it's actually quicker than a bike or skates since it doesn't need a lock and comes in with you.
Don't sweat the second rig. A lot of people carpool to the lifts, 10mpg and a short wheelbase is no way to attack the passes in a snowstorm. You'll meet a lot of people with AWD cars, and quite a few with already built Tacos and Runners to get to the hill. Bring a few bucks for gas and you're GTG.
Besides, unless you have a ready financial solution, you can drive the 40 and come out of college debt free vs loan and vehicle debt on a second rig. Dunno what your situation is, but in the long run like Dave and others have mentioned you're better off saving now and going big later.
The 40 is ready to rock, and it'll be easier to park than anything else, particularly a Tundra

Or...if you need more space, you could get a Chaser
