Nice sampling of threads... a 'la 2air
But you forgot one of my favorites:
Pivot Point Projection hitches are the only way to go.
After more than two years of Arrow ownership, here’s my take:
1. no sway from wind
2. no push from semi's
3. no wiggle from semi's and wind and road irregularities
4. no porpoising from under sized torsion bars
Rock solid. The whole rig feels like a single unit.
1. replacement parts unavailable except from factory in Romeo, MI
2. heavy, adds +200lbs to tongue weight
3. dreaded “hensley-bump” in panic stops
4. backing-up ‘wander’
Item 1 is a big one, as I discovered on our trip to YNP. Any problems on the road, and you're dead in the water until FedEx arrives. Lifetime warranty is great (getting them to honor it isn’t easy, by any means), but shipping cost is a real killer when everything about this hitch weighs a ton. The only real solution is to carry the “emergency kit”. I also carry a spare strut bar, now.
Item 2 might only be a problem if you're pushing your TV ratings.
Item 3 is something that may only effect folks with hydraulic systems. Even with max gain, and perfectly tuned brakes- I get the ‘bump’ in a panic brake. I honestly don’t think it’s a safety issue, more unsettling than anything else.
Item 4 can be a real nuisance. Until the receiver box settles to one side or the other, you’ve got basically no control over where your trailers going. Most of the time I can accommodate, and set up for it- but of course there’s that one time, and that’s when I bent a strut bar. Argh!
I’ve used both a reese WD with friction bar (like feeding a 'gator, hoping he'll eat you last), and Equal-I-zer. Even with the drawbacks of the Arrow, there’s no question, I’d take the Hensley (no experience with the ProPride)
btw- 'cost' isn't a con... we're talking about Airstream's
