Texan, That's exactly what I did. Once I saw that the unit had disc brakes/level up/Progressive EMS/leds everywhere/G614 tires I knew that was the one to buy and would most likely not fine another unit with similar upgrades for the $$
2018 Chevy 3500 LTZ Dually Diesel 4x4 CCLB
2011 Montana 3455 SA. 6 point level up. Disc brakes. Curt Q24 Hitch
Progressive EMS. Valterra tank valves. Sailun G637 tires. ARP fridge control. All led lighting. Mor Ryde IS
I checked the Henderson site in Oregon and the Mor-Ryde site in Elkhart and neither mention anyone doing I.S. Henderson does the Mor-Ryde suspension system such as the LRE 4100 AND CRE 3000 but does not mention I.S. You have to do a lot of welding and cutting for the I.S. so i doubt anyone wants to tackle that.
All I can say is that some folks on our SOB Forum just had the IS done at the Henderson location. As for the Colton location, I just took the info all the MORryde FAQa as to locations, maybe it was planned and never happened.
