I have always been a Chevy guy. But when it comes to MH chassis they suck!!! To make matters worse Workhorse took over. At first you could still go to a Chev dealer and they would order from Workhorse. Then you had to find a Workhorse dealer. nw the parts prices were raised and you had to pay freight. Then it got even worse. Navistar, the company that ruins everything they touch, bought Workhorse. They sold off parts of the company but the P30 chassis and even the regular Workhorse chassis became orphans. Some of the common items were not exclusive to the MH chassis so they are still available but lots were Workhorse only. My advice: Stay away from the Chev Workhorse chassis. If you are unlucky enough to have bought a short WB P30 it can cost almost $5000 to make it handle correctly. Too bulletproof the Auto Park can cost almost $2000. What a shame! If you really want a Chev then make sure the previous owner has done all the chassis mods. My last Chev unit had all the chassis upgrades when I bought it!
