2020 HD Standard bed / 5'er Hitch

[jjackkrash]

I currently have a 2019 GMC DRW long bed. I currently tow a big travel trailer, heavy equipment flat bed, dump trailer, etc., i.e., most things from the conventional hitch. But I foresee a 5'er in my near future. With the new tow specs, I am considering a 2020 3500 SRW as I think it would meet my towing needs without the DRW or long box. My big question is whether the new regular box that is supposedly longer is long enough to run a 5th wheel hitch without needing a slider hitch. I don't really have any interest in going back to an SRW with a long box. That is, if I am going to run a long box, I might as well get the extra wheels, IMO, but I also don't really want to screw around with a box that is too short for the job.  (I don't have any 5'er ownership experience so sorry if this question is a bit basic).  

Anyone know the answer?

I have a 2020 3500 SRW and I do not need a slider with my fifth wheel like I did on my 2016 2500. I would recommend you that you purchase a fifth wheel built with the maximum turn front cap which also helps to improve the turning radius incase you need to make extreme turns.
