I just purchased my RV, and read and re-read and re-re-read this thread before bringing it in for an alignment. :) Just looking at it I knew it had too much positive camber, and it had worn the outside edge of the right front tire in only 7000 miles from new. (After looking at the "Before" readings this edge wear was likely more from the excessive toeout than the excessive postive camber)
I brought it to a place that does mostly medium trucks, but also a fair amount of cars. I purchased the Ingals 59400 eccentrics and supplied them. I told them exactly what I wanted (at least +5 caster, +0.5 more RH caster, near zero toe, near zero camber).
They installed the Ingalls, and improved the caster, but could not get anywhere near the +5 that I asked for. They said even with these eccentrics in, caster was now maxed out.
Question: Should I look for another alignment shop? If so, does anyone know an alignment shop experienced with this exact situation in the Northeast? NH, VT, MA?
Here are the details:
2007 Gulf Stream 6211 Class C 21' on a 2006 Ford E350 V10
LF Camber was +1.4 now +0.4
RF Camber was +2.3 now +0.3
LF Toe was +0.61 deg (out) now +0.03 deg (out)
RF Toe was +0.63 deg (out) now +0.03 deg (out)
these changes I'm happy with, I would have preferred a little toe-in, but 0.03 degrees is pretty close to zero
LF caster was +1.6 now +2.9
RF caster was +2.3 now +3.7
well, it did improve, and they did get more RF caster, but I was really hoping for a bigger improvement. Do you think that this is all I will be able to get even with the Ingalls bushings? Or do you think the tech just wasn't skilled enough. I know they were attentive and cooperative, and they did understand exactly what I wanted, but enthusiasm without requisite talent doesn't always make the goal line.
The RV seems to drive straight down the road... we are headed on a 6hr trip Thursday (to race at Pocono) so I will be able to see how it behaves then, but it certainly doesn't have a strong "return to center" steering
any help would be greatly appreciated!
