[Gwenne & Len]

Rickst29 - Appreciate your reference to Marathon inflation per load specs. Will weigh the trailer. On the subject of WDH's I am respectful of Toyota's warning about not using them with the Highlander's frameless unibody. When we towed the 3124 home after purchase it behaved well. Tire pressures were 55. It was not a long trip and we didn't encounter a wide variety of road surfaces but the ride was definitely better. Will play with pressure increments over a local stretch of road encountered on our second outing that excited the TM with 65# inflation. Other than this issue the Highlander seemed to handle the 3124 quite well.
Am still intrigued by the potential of adding shocks to the TM and will check out an Airstream shock installation on an identical Dexter Torflex axle at a local dealer next week.
