Been meaning to post this for some time now. Due to the ever increasing weight of our camping kit, the Bighorn was starting to drag its bum about when we had it all on board so following some advice on a Aussie website.
http://www.exploroz.com/Default.aspx
I decided to buy some of these http://www.truckspring.com/air-lift-1000-kit-rear-60783.html
Buying them direct from the states saved me at least $NZ200 over what I would have paid for them in NZ. Their service was good & they arrived in about 12 days. Hint, ring them rather than email or fax.
This was half of the kit.

Installation was relatively easy, jack up the rear, axle stands under rear cross member, remove wheel, lower jack under axle to spread spring.

Follow instructions to insert airbag after first hooking up airline to it. Put top spacer in, threading airline thru hole, then thread airline thru top of spring mount & feed to chosen point of placement of air valve.

I chose to thread mine thru the chassis after first wrapping it in spiral nylon sheathing, & I put my air valves in the rear of the side steps, as seen in the third pic, the airline exiting the chassis just in front of the sway bar then looping down & around to come to the rear of the side step. My airvalve is just visible. These are just a schrader type valve & blow up with a bike pump or foot pump. The kit suggests putting them into the rear skirt, I've seen them on exploreoz in the rear steps.
The other thing I did which is not mentioned in the installation sheet was to put a small heat shield on the exhaust pipe adjacent to the left air spring just in case it got too warm.

I simply folded up a piece cut out of an old aluminium oven tray & attached it with a couple of hose clamps.
Before I load up I blow them up to 30 psi & let them down to 5 psi empty as it says to. When travelling less heavily laden I run 20-24 psi in them. The verdict after having them in for about 18 months. Bl**dy brilliant. A huge increase in stability & handling. Hope this helps someone with a weight problem.
Steve.

Sorry about the typo in the title, checked the rest but not that Embarassed

These cost me about NZ$160 landed at the gate, this included airmail post from the US, ask for US mail shipping not UPS which costs heaps more, at least to NZ anyway.
