Not sure I'd be to happy to do that... Those fins allow the bar to breath so it doesn't overheat, even if it is led, the bar can still overheat in the summer...
I have no clue. It's a single square tube the runs all the way across... I've seen a couple guys who took it off with a grinder, on my sport it sticks out on either side and with my steel bumper it sticks out like a sore thumb...
Ride and towing are both gonna be a little better with the longer wheel base, cost will be more, appearance is up to you, I like the look of them better than the short bed, but I've looked at a DCLB every time I look at mine...
Got the truck used, they came with the truck... Tires are Goodyear wrangler duratrac LT235/85R16, when I got the truck I think it had toyo mt 265/85 15
And any black vehicle is hot, especially in Houston summers, my dad had a black truck, I'm here to tell you that I will never own any black vehicle as long as I live in Texas...
Interesting... Mine does something similar under the hood, but it has to do with the intercooler for the supercharger... Not sure what would be running at the back of the truck...
