My wife & I purchased a new North Trail 22fbs(29'7 overall length, empty weight 4725#) a couple of months ago, its not a pleasant experience to say the least. It causes the Expedition to want to sway, not so much the trailer swaying. We have an Equalizer brand hitch, but I am just wondering if it is too much trailer for it. I pull it with my dodge dually & just drop it on the ball w/o any wd or sway device & It pulls just fine. I know yall will say, just pull with that, but that is not what I am looking to do. Will airbags help? I know the exp. has independent rear axles & coiled springs , unlike a truck with a solid axle & leaf springs, so I just chock it up to the 'soft ride' causing it. I like the Exp, but we are looking at trading it in and buying a 1/2 ton p.u. We just bought it in March and really don't want to take the hit, but we are figuring that is what we are gonna have to do. Would a 1/2 ton pick up would be sufficient? Anyone have any ideas? Thanks for your time.
