Upgrading RFMogul in Las Vegas, NV.

I have read where on three occasions, coach owners were forced to take their motorhome to SLC due to "not good" at doing the upgrade.

I have the upgrade kit in the garage and not positive about which SWM was installed. Coach across town.

Looking for someone who has already successfully installed the upgrade here in NV.

Any suggestions appreciated. SLC is 328 miles away, LAX is 268 miles.
