Again more great tips and suggestions. I'm a little concerned with the weight now if towing in the mountains makes a huge difference on pin weight. I'll get that checked next week. We've had the unit a year and camped about 12 trips, weight has never been an issue, half the time I forget its back there! But the mountains are a different animal, I will take the advice of those who have 'been there, done that'!
Even though we've been on a dozen trips, there is probably no more than 3000-3500 miles on the rig. Would wheel bearings need repacked after that? They are supposed to be EZ Lube but it seems a little early for that!
