It's one of those "matter of preference" things... after all... if you're doing an S10 swap... it's all about doing what you want and the custom
Some like the running boards to have about 2" or so of overall decline to the front and IOT achieve this, the cab needs to slope about 3/4"-1" to do so.
Cheers,
Ted
