We boondock for the majority of our trips.Get into some tricky areas where we have to keep the trailer from hitting the back of the rv.Didn't have a choice when I got the trailer otherwise i would have gone V nose and extended tongue.I added an extended hitch and it helped a lotI want to get one of these multi hitches for the truck and wondered if putting the extended hitch into this other hitch might create a safety issue.Trailer fully loaded is about 4600# and I have 400# tongue weightAdjustable hitch20190915_1421331 by 185 EZ, on Flickr

“Trailer fully loaded is about 4600# and I have 400# tongue weight”Less than 10% tongue weight is unsafe.

It probably has some sort of warning about using your own hitch shank. It probably could be done, if you calculate out the larger moment from extended the ball distance.But why not just use an adjustable shank-mount designed for this purpose? They even have a torsion-cushion version:https://genyhitch.comStandard:Torsion:

With that little trailer it would likely be ok, but why?Are you worried about Jack knifing your trailer into the truck too?

I want the multi hitch for the truck since I use both the 2" and 2 5/16" ball.Just wondering if I could use it in addition to my other hitch to extend further on the rv.I have hit the ladder on the back of the rv.I have had the top front edge of the trailer come very close to hitting the rvIt doesn't take much of an angle when pulling out of a site onto the road to get the trailer too close for comfort

I use an adjustable hitch very similar to the one you linked in conjunction with an APEX 8" hitch extension on the MH and just the adjustable hitch on the truck. The 8" extension gives me piece of mind that I won't hit the back of the MH and is still rated at 500lbs/5000lbs..

Any thought to having a fabricator cut off the tongue and building a newer longer one?

Advice about hitch extensions will go from “never, you’ll kill someone” to “you’re fine” on here.
My 2c is the weakest potential link in hitch extensions is the larger bending moment it puts on the receiver.
From a practical standpoint, I run effectively a 2’ extension on my OE 2007 Dodge hitch. Class IV I believe, with around 6-800lbs tongue weight and 6000lb trailer. Thousands of miles doing this with no ill effects and no bent receiver.
Just for comparison.

From doing a hitch ball extension vs literally extending the trailer hitch, I'll take the trailer hitch extension. Then and only then, is one able to truly Jack knife a trailer in tight situations.
It is pricier to do, need an excellent welder etc to Make sure it's done correctly.
Not asked by OP about this option,,,,
