Thanks for the ideas guys.
Here's where I'm at. I'll try to address all replies.
I picked up a 12 ton bottle jack and did a dry test on the trailer, with the assorted 2x6 and 4x4 cribbing I have, it worked fine.
My hi lift jack also worked fine.
I DO have the room to carry both, so will. I also picked up another 'spare' 14' chain. Plus a 3 ton comealong ( I love those.. just in case.. ). I already have a 4 ton electric winch. I carry a spare universal interstate battery with me on trips.. has side post and top posts.. will fit alot of trucks and tractors. My 'new to me' truck has plenty of toolbox space.. has 3 nice aluminum tool boxes in the bed.. one in the back near the 50g fuel tank in the bed, and 2 along the sides.
Got an assortment of hand tools.. usual stuff.. ratchets, pliers.. etc.. extra wire, terminal ends, and some spare marker lamps and such. both jacks fit fine.. picked up a couple extra ratchet straps now thaI have more deck length, plus a chain binder for my chain box. Picked up a dedicated 4 way lug wrench for the truck so i don't have to rob the one from the shop all the time now. I also carry a 15g air tank when tractor tripping.
welded up a step for my bumper reciever that is not used on that truck to make it easier to get into the bed.
I absolutely LOVE my 'the goose' gooseneck adapter that fits on 5th wheel rails. hasn't too expensive, has a lifetime warranty, and just like a 5th wheel adapter.. pull 4 pins and it comes out. has a free rotating ball that is replaceable by removing split rings and washers on the underside.
best of all.. that gooseneck pulls like a dream going down the road.. I already love it way better than my bumper pull. prodigy controlerl had no problems with it either. Finally got to road test the 4.88 rear end onthe interstate... to to about 73 she's about 2800 rpm. tached up pretty good.. but not too bad... keeps the exhaust temp up but the throttle is nice and responsive

Yep.. I think I'm gonna like that truck and trailer together.
