i have seen the rotating handles, i think you are talking about. that work much like the trailer jack up by the ball hitch. that you crank. but i honestly do not remember seeing any sort at local stores or online websites. granted i have not went looking for the specific type of turnbuckle.
doing a lot of seat time for road maintenance, i would say TNT (Top aNd Tilt) instead of a turn buckle on right side, it gets replaced with a hyd cylinder, and same thing goes for TOP link. and you adjust with a couple hyd valves/levers.
i never realized it, till another post awhile back showed up. but getting correct size "tilt" cylinder. that will allow you small adjustments both up and down. is necessary. and if you buy a kit, you may just get a cylinder that has a long rod. that only levels or goes down for a large right tilt. vs being a shorter rod on cylinder that allows a little bit left and right tilt but no large/longer titling.
the cost of hyd cylinders for TNT and then possibly needing another 1 or 2 rear remotes and valves can get a little costly, but time wasting gas as you deal with manual adjustment. vs moving a lever that lets you adjust things as you are moving.... and high chance for a much better final results with TNT vs manual adjustments.... TNT could pay off fairly quickly.
