Somebody has got to have a trick to changing one out ? I have a 2005 RE 300 with pass thru cargo bays . We are having problems with building air past 30lbs . So I checked governor and so I went to the air dryer to see if it recieving any air . I can't get to it . The cargo bay is built around it . I open doors and look and there is a box covering air dryer . I think this is going to be so easy . Remove cover and there is no room to unhook the air dryer . In fact lttle room to even remove it . So unless someone can tell me an easier way I may have to do some sheet metal work .I don't want too because ther is like 15 1/4 rivets holding the panels on . Thanks
