I just finished a 9k+ trip to Alaska and back hauling my 25' Arctic Fox
5th Wheel with my 03 2500 HO 6sp. Went as far North as Coldfoot, Alaska
(diesel @ $3/gal). Not one problem with the truck or fuel (other than
my upcomming cc bill).

My question is about the alignment of the trailer axles on the Fox.  I
did have two flats on it.  It seems the rear axle has inner tire wear
on one tire, and outter wear on the other. Seemed to be a cocked axle
to me, so underneath I crawled and measured the distance between the
axles at the same point on both sides.  The differance between the two
measurements is 5/16".

The trailer seems to track straight, the wear on the front axle's tires
seem normal (with 20k miles wear).  It seems the springs are pinned to
the axle mount, so it wouldn't be as simple as loosening the axle from
the springs and moving the axle along the spring.

These are Dexter Axles with Double Eye leaf springs.  Now, thinking
about all the pivot points of the center hanger with the bracket,
shackle link and the spring, I guess the axle distance floats depending
on load.  Is that right?  Is there any adjustment on this system?

Next question is on the no-name shocks. One pissed its contents (front
left), and with the hundreds of miles of dirt, gravel and poor asphalt
roads, I'm suprised its only one.  I want to replace them all. I'm
looking for reccommendations for trailer shocks.
