I'm pulling a 2014 Arctic Fox 25r with a 2015 Silverado 2509 HD.
Sometimes I scrape the tailight of the truck on the fiberglass nose cap of the trailer when backing it in to my driveway. Its a narrow street and I'm not 100% consistent in nailing it in on the first try without jacknifing. Will going from a 12" long shank to an 18" long shank buy me a bit of extra clearance between rear corner of truck and nose cap and better backing control?

It will help. To hit the nose cap of the AF on the tailgate, you must be pretty much jackknifing the trailer, eh?

Won't that make for a longer "lever" as far as the hitch goes? Meaning, you will be putting more strain on the trucks hitch to get the same WD. But, if the hitch is up to the task, sounds like it'll help with your ability to turn tighter.

Do you remove the WD bars before doing the task?

I have to do that with my TT when I park it at home.. Just because of the angle of the driveway I have to go up, there is an extreme angle as the trailer goes up the driveway while the truck is still on the street.

Good luck! Mitch

Doesn't seem so, but obviously I'm cranking it too far.

Oh yeah, i remove the wd bars when I do tight backs. Questions answered on e-trailer.com seem to indicate that wd won't be affected as long as the tongue weight is within the limits of the shank's capacity. It's made by equal-izer which is the wd system on the truck.

What do you think about putting a front hitch on?

^ Weight distribution and moment arm, transferred load, stress o the hitch receiver, etc will absolutely be affected by the distance from the receiver to the hitch ball and distance from hitch ball to truck axle.
How much is the question? 6” longer won’t have a “huge” effect. Although a 12” long stinger shank is already fairly long.
If you need it, you need it, but seems like an extreme jack knife or grade break is likely the cause of the issue. Presuming it doesn’t happen in any “normal” say close to 90 deg jack knife backing.

Whatever you choose to do, get a proper 2.5” shank if you don’t already understand the importance of that. Towing heavy and hitch reducer sleeves don’t mix well.

To your original question, of course it will move the trailer further from the truck and provide more room.
Unsure of the “more control” question, but you won’t notice the difference in length in “how” it backs up.

Haven't even thought of it, but would certainly entertain that possibility. Tell me more?

That's how they move them at the distribution yards....They move passenger jets that way too.
