Beings you are unfamiliar with big vehicles and mechanics and the particulars with different brands and years of trucks, your truck may be and probably is normal, nothing wrong.
First, you likely didn't get death wobble or your post would read "Thought I was going to die!"
Second, 2nd gen Rams are old school in most ways. You got the end of the 2nd gens which were introduced in 1994. You have a new 20 year old truck combined with Dodges being less "refined" than their GM counterparts and certainly mid 2000s Toyotas.
IMO you still got one of the better combinations for your use hauling a camper and hat truck certainly is not overloaded with that camper on it. Even with every suspension mod known to man, it will handle like cr@p compared to a tundra tugging a pop up.
47re, not the best trans, but suitable if maintained and engine left stock or close to stock.
You're right, best to get someone qualified to check it out. Even as simple as finding someone who knows how the truck should perform with and without the weight on it.
Like a friend or someone on this forum from Denver.
Aside from having extremely low mileage and potential issues from sitting a lot over the years, I doubt there is anything really wrong with your truck other than basic setup or your expectation of how it would handle. A 2nd gen Dodge dually 4x4 is one of the rouhgest riding vehicles made.
That's good news.
You'd probably have a heart attack with my camper on my srw truck! Lol. It's like driving a marshmallow!
