Tips on Sway
Several things increase the chance of sway, the biggest is too little tongue weight
. Ya gotta have at least 10% of total weight
on the tongue. Buy a 350 lb range bathroom scale at the "Big Flea" for $5 or so and get your jack up on it. 15% is better, any more may stress your hitch, check the rating stamped near the receiver. Your 17.5 BigFoot
will weigh at least 3000 lbs loaded, that wt. shown on the closet door sticker is "Empty weight"
To stop sway: a) Apply trailer brakes
only and/or try to accelerate. This can get a bit scary going down a hill but sometimes it's the only way. Years ago we spun a Chevy Blazer and a 26' Airstream 180 degrees on the interstate in Utah when a triple truck came by at 80 MPH and everything got out of hand. No injuries, but my wife refused to ever drive with the Airstream attached again.
BTW: Towing speed limit in CA is 55, I have been given a reminder of that already...
Maximum safe speed on NEW trailer tires
(Marked ST for special trailer) is 65 MPH when inflated to max pressure on the sidewall
Trailer brake are mandatory for anything over 1500 lbs in CA.
And Last: When my s.o. and I are in a campground there is at least one Asian.....
