By "slide stabilizers" do you mean something to put under the slide itself? That might help a bit, but you cannot put any weight on them, as that would push the slide away from its seal to the camper wall.
The StrongArm stablizers will help a lot. Are you getting them put ont he back as well?
I was looking at the slide stabilizers at Camping World and I thought the same thing you mentioned, and I would be concerned that the slide would lift off of the gear rack. I was going to check with other people that use them and see how they work for them.
As for the JT's, they're being installed just as they are at the factory, welded to the frame; 4 in the front and 2 in the rear. I couldn't beat the price so I'm hoping they do their job. It would make DW very happy.... and you know, if momma ain't happy, nobody's happy.
I also have used a tri[pod under the pin. It helps when in the bedroom, but not the rest of the trailer.
