I am a new member but have been lurking for about 6 months so.....at the risk of being kicked out, I have a tire question. I purchased a new to me 2009 31 foot Keystone Hornet TT in September 2013...
With a 2011 mfg date, I wouldn't be too concerned at this point UNLESS you're planning an extended trip. Then, just for peace of mind, I'd replace. Usually around the 4 - 5 year time is when you need to start thinking tires - we're usually around the 4 year mark. Seems we always plan a trip about that time and rather than fret, we just bite the bullet.
