Joedoh, thank you for the reply. I understand what your saying ... there are a lot of factors that all influence the out come and no short cuts to getting there. I will have to do some test fits and measurements. I believe that I would be happy with a small tunnel... just don't want one crazy big taking all the foot room. And this is certainly not a one size fits all type of thing. Previous measurements that I have read about cab placement did not match up for my build. Think I have an odd frame and/or truck... unless I got it all wrong.
