my buddy owns the truck and i built a lot of it . its a c&c frame !
had a dump bed on it . and measured out at 135"
i have 4 k30 trucks my self so i know them just a little bit .
he wants a bed swapped out for a military trailer bed . then we will drop the rear just a bit to get her butt down a hair . thats a 4" flip kit . prob swap to a 2.5" flip and be super happy then .
