I have added airbags to the rear suspension of the truck. Until it is out of warranty, there is not much else I will be doing to it so I don’t void it.
In April of 2016, after having a blowout of a tire near Albuquerque, NM, we decided to go ahead a little early with upgrading the tires, wheels, and axles on the trailer.
We are running on Goodyear G614 235/85/R16, which has a capacity of 110 psi and a load rating of over 3,700 lbs. We also upgraded the wheels to ones that are rated for the higher psi.
Tires and wheels were purchased at Discount Tire. I highly recommend purchasing through them. This is my second set of tires, and because I had two tires damaged in the blow out, both were eligible for the road hazard warranty that I had purchased, so I got a refund towards the purchase of another tire.
So, I purchased:
4 wheels at $90
4 Tires at $293
Warranty/road hazard replacement/lifetime balance $256 for all four tires
32 new lug nuts (gotta sparkle) $48
So, with taxes and such total was $1,662.95
Replaced both axles with 7k axles, upgraded leaf springs, new brakes, new hubs, new wiring for $1,600.11, which is a considerable cost savings, since I have seen the 7k axle assemblies from Dexter cost $1,000 a piece.
Here is how we deal with stabilizing the RV while setup.
