I know you wanted your comments based on a f150 and a Reese revolution which I have neither, however I have a shortbed gm and a 5th wheel with a slider and in 6 years towing this way I've never used the slider and this is the farthest I can turn with out engaging.
If you need more then that then there's something wrong.
In many cases a pull up and re back is needed.
A camping friend has towed a flagstaff 5er with a Reese revolution without a slider and f150 as well for 6 years and not had a problem.
Imo the whole point of the revolution is to not need a slider.
I think your wasting money.
