I just finish a 8000 miles trip from Michigan to California.I have a 35 ft Cougar 2009. I had Marathon tires put on with the new sidewalls before I left.Some of the roads were very rough and temp. were at over a 100. Tires never got over 110.
My problem was a rough and bouncing ride. The worse was when I went over a bridge the trailer would bounce and sometime throw us around in our seats. I tryed keeping the front gray tank full to give a little more tongue weight it helped a little. I have Chev. 2500 diesel also Demco pin box, easy flex spring system and monroe shocks. It is like I need better shocks. Anyone have any ideas.
Thanks

Is your truck lifted or lowered at all? My old toy hauler would do that when we headed to South Dakota but my truck had 13" of lift lol.

I had a similar issue and installed Timbren Bump Stops (rear only). I originally purchased the standard Timbrens and my bounce was almost gone, but still noticeable, Timbren sent me a set of the severe duty Timbrens (no charge) which completely solved my bounce issues. I think on my truck the bounce is caused by how high the rear of the truck sits and the amount of travel.

Air hitch might be needed. Best idea for a smooth ride and long lasting fifth.

I have installed a set of Timbrens and still have a bouncing issue at times. Seems to happen when crossing concrete bridges. The 5er starts to bounce and then gets the truck bouncing a bit. I usually let off the gas a little and everything settles down. I'll be interested to see if there is a good solution for this.

Tires determine the final spring rate of the suspension. The new tires fully pressurized are definitely making for a harder ride. If your weights allow it, try a slightly lower tire pressure. Outside of working on the trailer suspension that's your only solution.
Air hitches and pinboxes will stop the transmission of those bumps to your tow vehicle, but the trailer is gonna keep on bouncin'.

The difference will be more floating than banging from the hits the truck is taking with an air product.

Make sure the trailer is level. Increase your tongue weight to 25% if possible. 5th wheels handle best if they are level and tongue weights are more than 20%.

In our case, we didn't have the correct hitch for our Carriage. We were brand new and we tried going with something "new" and "innovative" and had the same horrible ride you are talking about. We were actually down to 45 MPH sometimes just to be able to stay in the truck. We turned around and drove 700 miles back to the hitch manufacturer and explained our dilemma. The owner was really great He not only gave us our money back saying he didn't have anything strong enough for our sized rig but let us stay in his lot while we drove to a nearby Camping World did our research and bought a Reese Hitch rated for 22K. We brought it back, installed it in his lot then headed out again. What a difference! Hope this helps some. Di

Look at the centerpoint equalizers. Made a WORLD of difference on my trailer. between that and the triglide I (usually) don'w even feel RR tracks on the trailer. What little front to rear action I have left I wouldn't even call chucking anymore.
