That is a nice floor plan camper.
You asked what to look for in the camper. A water infection. See this post I just did tonight to another new member asking the same thing. Just because you cannot see water stains or smell mildew in the camper, there is more to this.
Another note. Your sellers ad stated this "Good tires". When we are talking travel trailer tires, the rules change as to what is good, and the amount of tread left is not a good indication. First to look for is the age of all 5 tires. Yes, including the spare tire.
There is a mandated 4 digit DOT date code on the sidewalls of the tire. It is only on one side, so it may be on the inside and you have to crawl under to find it. See here on how to read the code https://www.tirerack.com/tires/tiret....jsp?techid=11
Trailer tires are recommended to be changed every 5 years. This is rubber break down issue, not due to mileage or wear which can also cause tire replacement. If the owner swears his 5 or 7 year old tires are Good as the tread is really deep, he is not familiar with the issues that create trailer tire failures. This is different then auto tires.
Putting 5 new tires on the camper from the get go can be over $500.
Your older Durango will have issues towing this camper across the USA. Not necessarily in the pulling area, but being able to handle the loaded weight of the camper. The camper when loaded can reach 5,500# which is the GVWR of the camper. The 4,150# number is the dry (empty) weight with no cargo, no LP gas, no battery or any extra options included above the dry weight. The camper can easily go over 5,000# when you load it even with light gear. Be looking for a truck to handle the full 5,500# of the limits of the camper with a potential loaded tongue weight of 700# to possibly 800#. That camper starts with 13% loaded tongue weight which is good for stable towing, but the truck has to be able to hold it up.
If you look at the sticker you posted, Dodge lists trailer weight as 4,650#. That means with an empty truck, 1, 150LB driver the largest trailer they recommend is 4,650#. If you add more gear in the truck, you have to take that amount of weight off the truck tow rating. And that is before checking all the axle ratings and the receiver hitch in the back if they can handle the campers loaded tongue weight. If you get that camper, you could very well be looking for a more capable truck.
Hope this helps and glad to explain more as needed.
