Find a public scale. Make sure your rig is loaded as when traveling. You'll need to get total weight. Then drive off stopping to get weighed as each axle leaves the platform. Then drop the trailer and get the trailer only weight. From here you'll know what is going on weight wise.
I struggled with bouncing for years. The back of my 5th was a disaster area after a rough section of road. I found two problems that weighing the rig helped me figure the problem. First the Eagle Half Ton was pressing almost 20% of its weight on the pin. What this was causing the rear suspension of the truck to bottom out. This would launch the pin box up as we passed over a bump. Thus forcing the rear of the trailer down. As the trailer axles passed of that bump, weight shifted forward pressing down on the pin, causing the truck to bottom out again. Any bumps were just miserable.
First thing was to replace the 50K miles factory shocks on the truck. I opted for Bilsteins. That was an immediate improvement. I then emptied all the tanks on a trip which improved the bouncing. Next I cut the bump stops on the truck rear axle for a few more inches of travel. Thus another improvement. And last the pin weight needed to be reduced some. Since my fresh water tank is behind the rear axle, I can add balance weight to unload the pin. I found a half tank (20 gals or 166lbs) worked best to dampen the bounce even further. I prefer to hold no wore than 30% water or 14gal/116lbs.
These changes have altered the ride significantly. Its still a 3/4 ton truck hauling 8000 pounds of RV. Nobody said it would be like driving a Cadillac.
I developed a fundamental spread sheet that does some calculations for determining GVW,pin weight and such. Message me if you're interested with your email address, I'll send you a copy. Safe travels.
