Proven Design is great.
I've got two snow flaps and a set of flat bed truck flaps.
The stiff rigid snow flap is pretty good. I have the ManBearPig model. Lol
I've swapped it out to try the flexible flap. Two seasons on each. Not sure which is better. Both are fine.
Ya was looking at pd flexible snow flap, I had the harder snow flap on on my pro with the 3" track but found it was too stiff, was a pain in the a$$ when stuck.
