i had a ford ranger 4x4 that i put a 302 in it. had 4.10 with 31" tall tires. no insulation, no mat on the floor. truck was just an off road bomber. took it on a 700 mile round trip in the middle of august. was the most miserable trip i ever took....including riding a 600 mile trip on the bike in november......in the rain the entire way....
