Forgot: I have heard fifteen years cited as a wear-by date (unofficially) on torsion axles (less if the trailer is rarely used). The Al KO and HENSCHEN sites list measurement procedures for determining correct ride height. DEXTER probably does too. There's room to play with starting angles to dial in what is wanted.

Thanks for the info on the air system. Am impressed (as always, by fabrication skills). And a commendation for what so few are willing to do: proper axle weights FF-RR and side-side.

I saw the same mpg with my truck [sig] as with a half-dozen other 2nd & 3rd Gen Dodge CTD owners pulling 31'-34' all-aluminum aero trailers: 13-16 mpg (speeds from 55 to "about" 65 mph; backroads and Interstate). Some were 4WD but mainly 2WD. My combo was loaded to .92 of capacity when fulltiming and the axle weights revealed a pretty even split of vehicles at around 7,500-lbs each; just over 15k gross. It'll be of interest to many the record of this 5'er for FE.

Have bookmarked and will be sending others to this thread!
