Swingout extensions?
I have maybe a max of 3/4" clearance between my dually fenders and my front jacks. I have dually swingouts. I see where eTrailer has extensions to mount on the swingouts. Item # HJ54FR. It would posit...

3/4" is plenty :). That is about what I have. On my previous truck and camper (F350Dually and 1996 BigFoot 25C9.4), the Happijack swingouts were insufficient for any clearance. I made extensions, by bolting a piece of 2 x 2 steel tube between the jack mount and the swingout bracket. My concern was that the further out the jacks are, the more torque is put on the jack mounts, trying to twist them off. They are not well designed to resist this kind of load. The stock swingout puts them out about 6" or so, adding 5" will nearly double that offset torque.
On my extensions, I welded 1" tube across the camper from one extension to the other, so that the offset torque was resolved between the two extensions and not transmitted to the camper jack mounts. It worked without problems for 15 years when I sold the camper to someone with singles, and he took it off.
