Jon and the rest of you folks, thanks very much for your concern. Being a rookie, and unmechanical, this is all foreign to me. I have the 2009 Bighorn 3400RE, so if you look on the heartlandrvs.com website under specs, you will see I have 16" aluminum rims, and E rated tires that max at 80lbs psi. So does that mean I am still over the pin weight or just under? I do have those wonderful Mission tires.
trucknutt, I have no clue what you wrote, but I have called the installer "Camping World" of San Marcos and they are calling Pullrite tomorrow for directions. I am not sure if I have the universal or the removable rails. I will ask. All I know is it was expensive. I got the superrail mount kit #35736 for $409. Where do I find these charts you mentioned? Hopefully they will fix it so I get a smoother ride. I don't think I can take any more epidural cortisone injections in the spine. I am starting to get discouraged for sure. We are planning a 11 day trip starting on Thursday to represent us socal folks at the Central/NoCal rally in Jackson. Then on to wine country rv resort and Pechanga for the socal rally. I may need a gurney to carry me off by the time we are through. I love RVing and have shared many trials and tribulations, but I am starting to wonder now how much longer we can continue if the ride doesnt smooth out somewhat. Darn, just as I was starting to get it. Well, the beat goes on. Bah humbug! We are having so much fun, hope it never ends.
