I started a similar build, then considered selling- why I am not sure. Had a local Expo fella come take a look at it, and decided NOT to sell. I started with an '07 PW, added the new '09/'10 steering bits per Don Thuren's advise, added his links and track bar and stabelizer. Fitted 35s (33s are stock)and a Flippac. Then added a 1" front spacer for leveling, ditched the 35s, went to 37s with only rubbing in the rear fenderwells. Ordered a Ute bed, here now waiting to install after moving the Flippac to a M101. Fitted ram assist last week, and now removing heims from steering bits and fitting tierod ends. Also fitted a Ranch Hand after a bit of altering for the PW- which they told me it 'wouldn't' fit. Hopefully to be finished next week or two, and plan to never sell it. It is the most versatile truck/4x4 I have ever had which is waaay too many over the last 40 years of driving.
As far as weight being an issue, my ball joints are already showing slight signs of wear at 18k miles. They are a weak link, and hate big tires. So, one last item to address in another 10k miles or so. I cannot say enough good about the PW. Rides great on road, and extremely capable offroad with tons of flex with sways disconnected. Reconnect at the touch of a button, and back to highway cruiser. Milage sucks, but 400hp and 37s w/ 4.56s it should. One last thing, being an engineer. These trucks were designed from the getgo by a room full of engineers, and not just a truck with parts thrown at it, hence very capable from the start. We can move the bias by altering, but do not have to design from the ground up. Just saying...
