I am new to the forum and have been towing a large pop up (2003 Coleman Niagra Elite) since 2013. I recently upgraded to a 2017 Jayco 28 foot Travel Trailer. Dry weight is about 6,000 lbs. I have been taking some practice runs with it and at about 60 to 65 mph (Dry) and I started to experience a little bit of sway. Shank and hitch are all installed properly by RV shop along with my Equalizer WD. I wanted to know if anyone on here has had any true experience with the Hayes Sway Master Electronic Sway Control and if it really works and if it will be beneficial to get one. Also will adding some sand bags to the front trunk to get me close to the 600 lbs (10%) tongue weight will help. I don't carry much gear so everything in the front storage area is about 100 lbs. Any advice is welcomed.

you need to add 300lbs more ... :-)

I was thinking that I would add Sand Bags in small increments. Menards carries what's called "Sand in a tube" and they are 70 lbs each. I'll probably start out with 4 of them (280 lbs)

It's been windy. Are you sure it's not just crosswinds? We saw a lot of different combos with different hitches coming home Saturday. They were all getting blown around as much as we were. Our 28RLS tows great without any sway control but we do feel wind gusts and cross winds when trucks pass.

I like Jayco, but I am really disappointed that they would sell a trailer that needed hundreds of pounds of dead weight added to the tongue. Are you dealing with actual weights, or brochure bs?

Actual weights. I am kind of a safety but so I have been taking this thing on test runs about twice a week before I commit to putting my family in the TV. The Equalizer WD with 4 point sway control works phenomenal but the Jayco has a lot of butt bebjnd thd tandem axles and sometimes catches a crosswind at 60 to 65 mph and i can feel it. Which is why I want to add weight in increments to get good balance in weight but also while leaving some room for our clothing and personal belonging like clothes etc. I was told that even with the equalizer weight distribution hitch setup that I would still experience a little bit of sway just because I'm towing a long travel trailer. I was hoping that the Hayes electronic sway control wood assist in eliminating some of that sway

By the time you are loaded for a trip you will be right around 7k lbs. you want to be at 12.5% for tongue weight (10% isn't enough!). That would put you around 875lbs. I know you came from a PuP, but you will be surprised what you take with you even if you don't think it's that much.

Installed a Hayes Sway-Master last year and it's working fine on my rig. The 23.5' Oliver travel trailer weighs in at 4950 pounds ready to camp with empty water tanks with 450 pounds tongue weight. TV is a 2016 5.7L Toyota Tundra without suspension modifications. Not using WDH.

After installation tested the Sway-Master at 55MPH and sway dampened in 1 1/2 oscillation. Towing in high gusting crosswinds on I40, TN plateau area at 60MPH, and sway dampened within 1 oscillation.

The Sway-Master uses a GPS to sense speed and operates above 45MPH. If GPS signal is lost, the Sway Master is active at all speeds.

Talk to Hayes to be sure sway master is compatible with your TV.

Thanks for the info. I already installed it on my A frame of my 2017 Jayco
28 ft TT. 6,000 pounds dry weight. TV is 2008 GMC Yukon Denali 6.2 Liter with K&N Cold Air Intake, Flowmaster Cat Back, upgraded Trans Cooler, NAPA Ultra Premium slotted Rotors and Premium Pads, Bully Dog GT tuner, Equalizer WDH, Quest Electronic Brake control. I am going on a 100 mile road trip to a campground for memorial day weekend. This will be the first true test. I will keep you posted and let you know what I think.

Is there Quest brake controller the same module used in the current GM pickups? If so it is incompatible with the Hayes system (was very disappointed to find that out as the idea of basically ABS traction control for the trailer was very enticing to me)

No. It is aftermarket. The problem was with the integrated brake control on the GMCmodels from 2015 and up I think. Hayes says it was comparable. Plus I took it on a 20 mile round trip test run on I80 here in Illinois and has some cross winds of about 30 mph. She held up fine. Totally confident now for my memorial day weekend and 4th of July week.
