The ride when unhitched is STIFFER THAN A WOODPECKERS BEAK .
But, we use our truck almost exclusively as a TV. We do use it at destination areas.
Would I step up if I were to buy a heavier at hitch model? Yes. Ours is plumbed for front closet washer dryer but not one there. We run packed for months at a time.
Here is a tip this was provided to me by another poster on TDR; change your tires to a heavier load carrying ability tire and lower the air pressure.
If you are using the 17" stock size tires and wheels these are only rated for 3195 LBS at 70 PSI. I did not go to the 19 inch tire and wheel that a lot of the TDR folks use in towing but I found these tire and wheels to suit my needs.
I have changed out my tires and wheels to Nitto Dura Grappler tire which is a 285/70R/17 126R and Mickey Thompson Sidebitter II wheels. The tires are aired to 70 PSI which will support a load of 3415 LBS and the wheels are rated for 3640 LBS. I run the front at 50 PSI which has a rating of 2755 LBS which is more than enough to support the front axle load. I than will air the rears down to 45PSI when I am not towing the trailer for extended periods.
The truck ride is a lot better than driving around at 70 PSI in the rear all of the time.
