Like some say, it gives you more room, that's why sooner or later I'm buyin a kit and putting it under the bed. Some people put S-10 gas tanks under there beds also, instead of buyin' a new one, which is specifically made for between the rail behind the rearend. I would think it'd be better under the bed btw the rails because then it's less likely to get punctured in a crash, and it's further away from the engine which can always start on fire. But that's me, I have no idea which way is really better, you'd need to test both ways to see which one held up better. It just comes down to: do you want more room? or do you want it stock looking?

If you're clean, then you're not a 'Man' If your truck is clean, then your truck is a 'Queen'.
