Just in case you are still looking for a cover, I have a one year old Calmark (custom made for my 5.0 TA) for sale. I am building an RV/mower/storage barn and don't need it any more. For the few months I did use the cover, it worked great. contrary to what some others say, it went on relatively easy (did it by myself at 69 y/o) and didn't seem to rub any finish off the RV. If anyone is interested I am selling it - make me a reasonable offer.

I was in your town once. I shelled out a u joint on my 78 Bronco and bought one in the NAPA store. A fella named Tiny put it in for me at a used car lot with a garage and hoist. Nice guy. Said there were turkeys " Lord a plenty" in that area. We don't have a cover we have a building but if you're in Eastern Iowa and need a mechanic, contact me.
