Just to followup, went to another dealer (not my Jayco dealer) who sold Equal-i-zer and Blue Ox. I was pretty set on the Equal-i-zer walking into the shop, and despite the salesmans efforts to steer me to the Blue Ox (which cost $150 more) I walked out with the Equal-i-zer with 1000 lb bars.
With a little help of my neighbours auto-shop I got it installed and setup myself. First tow, with no water and quite a bit of wind was much better. On our way back I towed with 3/4 fresh water tank and it towed even better.
Which has me thinking - we travel light. We basically added bedding and our car camping gear and some stuff in the fridge. I don't think it could add more tongue weight with what we got in there. Did some fresh water increase the tongue wait, perhaps giving me a better ratio?
Maybe only the scales will tell, but much happier with this hitch!
