Don (Gunnyusmc) offered to give me a hand yesterday...
In 4 and a half hours (including lunch!) we installed my rockguard and two axles.
The rockguard installation made a lot more sense once I received the hardware kit! When I first posted all I had was the rockguard itself. Thanks to balrgn for the photo showing the hold downs and other pointers.
The axles were easy once we figured out right from left and which end of the shock mounts where. Just jack them up and bolt them down. Had to jack up the trailer quite a bit higher to remount the wheels.
Don, call me when you are ready to install your awning.
