I need to replace some slide out seals on our 2011 Montana, both the wiper seal (we have the double, an inner seal and an outer seal) and the ones on the perimeter of the box (do not know the proper name for these). When our Montana was new and for a period of time, I would clean all the seals and then apply 303. At one of the rally seminar’s, someone said all that was required on the seals was just to keep them clean. Had I continued to apply the 303, the heat and weathering may not have affected them as much. So my question is: what is involved in replacing these seals? Has anyone done this before? Do you recommend taking the rig into a dealer?
