The flex in the HF tongue was always a concern to me and it is short to boot, so it will be absolutely necessary to lengthen and reinforce the tongue in my opinion.
I have reinforced the tongue and added 18" and the trailer tows and backs up so much better.
I dare say 24" would not be unrealistic with a bike platform on the front to keep the bikes out of the tow vehicle.
It does add to the tongue weight a bit !
It was not extremely difficult if you have a welder ( person) with a welder (machine) it is a bit easier but can be a drill and bolt project also.
If you do add a 2x2x1/4 square tube it is real nice if you can run it all the way to the rear then with a little shimming a class 2 1 1/4" drawbar can be added to the rear. This mini reciever could allow for a rear removable bike rack or cargo platform behind the trailer
Now get ya one of these
