Since Crossroads no longer makes the Rushmore and has itself been acquired by another company Iíve had no luck finding this information. I have an idea of what Iím going to use but thought I would at least try to see if I could find out if anyone on this group might have one. Thanks again for your interest and willingness to help.
You mention Superflex, which is a brand of TPO roof material... you did not state that the roof material has been replaced, has it?
There are two types of roofing material that are used on RVs; EPDM and TPO typically that generation of RV used the EPDM membrane. You should identify which material you have, and we can make recommendations from there. It is important to know.
