I have a ProPride and LOVE IT!!! I have towed from the East coast of New Jersey to San Diego via the Appalachians, Rockies and Sierra Nevada's - and just recently towed back to Maryland via the same route.
Rock stable at all speeds and even with big cross winds (55 mph cross winds on I-70 in Nebraska on my West bound trip during the spring) - I have NEVER had an issue but know for a fact Sean supports his product - TRUST ME as he gave me his personal cell phone number in case I had any issues when driving on my first cross country trip AND when I needed stronger support bars during the original install he had them overnighted!
My 25FB Classic tows at all speeds ROCK SOLID and the ProPride is very, very easy to hook up too - if you need more info then that go ahead and PM me...
Sean's supports the Pro Pride - and I SWEAR by it as do many, many others.
I highly recommend a ProPride and the support that Sean provides is impeccable.
