Wanted to get vehicle specific info on this subject. I have a 2007 Jayco 19H TT that we will be taking on a 14 day road trip in June/July, and typically take quite a few trips per year (had a new daughter in December so our camping is slow right now). I have been towing it with my CM with Airlifts and a Toytec AAL without any sagging issues but have decided that the benefits in an emergency situation make the WDH worth purchasing. Trailer has a GVWR of 4550#, with a 15% TW that would give me around 683# TW without anything in the bed when fully loaded. I am looking at Camco WDH's with 800# bars and 1000# bars. The 1000# bars are about $40 less and have more wiggle room, but are they too much for this setup? Can I jump up to the 1000# bars or stick with the 800# bars?
