The truck feels heavy with the camper because, well, it just is. The Taco, like my truck has about 1,100 lbs cargo capacity including humans and beer. A loaded Eagle, depending on options like water, will take roughly half of the 1,100. With all your gear, human(s), dog(s), beer etc. you are magically at or exceeding the max cargo capacity of the vehicle. Air bags help keep the truck from sagging, and do eliminate some sway. There are other posts on WtW indicating folks had good luck with Deaver spring packs, good quality shocks, and other methods like timbrens, supersprings, hellwigs etc.
You can put lipstick on a pig, but it is still a pig. The truck was designed to carry a certain amount of load...period.
I tried timbrens, but they made the ride harsh. I have supersprings now - they raise the back end to match the torsion bar lift I did in the front. With the camper on, the truck sits dead level. The truck still feels heavy, especially on the back roads. I take it easy, and all seems ok. I did a little 4 wheeling in Moab area this year, and all went well, but I was always conscious not to go too hard for fear of breaking something. I will try some better shocks next year, Bilstiens for all 4 corners will only cost about $250. I think good dampenining will help the rolly polly feeling.
The other thing to be concscious of is where you load stuff - try to keep heavy items as close to the front of the camper as possible. I generally carry my 6 gallons of H2O behind the seats in the cab, along with my tools, a small cooler, drinking water and beer.
A lot of folks here have Tacos with FWCs or ATCs on the back. They are great trucks, and guys like Kodachrome are in their rig for extended periods of time. Maybe ping him for some thoughts.
When I purchase my next truck, I will most likely go fullsize 3/4 or 1 ton. It really seems to me the wisest decision.
