I had a '95 T100 and it was a great truck! I owned it between 106,000 miles and 186,000. Now my brother drives it. I averaged 20 mpg in a full size 4x4. No major issues. Always started. Only issue I had was gas tank rusted away, but I replaced with a used one and it's still going. No complaints here.
Gas mileage in full size 4x4 and plenty of power as well. My new Tacoma with 4 cylinder gets same mileage but is tiny in comparison and has much less power.
