The answer is in the dry pin weight of 2950. That is going to be 3500-3800 when loaded. You need a dually. If you load really light and put in an aluminum Andersen hitch you might squeeze by with a 350/3500 SRW. 250/2500's should not be in the conversation.
I am going to a Cat scale to today to weight a similar size trailer that starts with a 500 pounds lest pin weight. This is to check that I am under rear axle capacity on our SRW 3500.

The Montana's and Alpine's are pin heavy rigs. I bypassed them for that reason as I already had a new 3500 SRW truck.

As you can see they are similar in size. Keystone has however placed the axles further to the rear shifting more weight to the tow vehicle. I found that the new Cardinals were similar to the Keystone products regarding heavy pin weight. Cedar Creek and Big Horn got on our short list based on our desire to tow with a SRW truck.
You will also find that you will max out that 15.5K GVWR easily. I have a 3050 carrying capacity and you will have only 1880. Filling the water tank with eat up 535 pounds of the 1880 CC. They(keystone) should have given the trailer at least a 16K GVWR instead of the 15.5K, actually 16.5K would have been even better.
People looking at new trailers should to learn to look at all these numbers and understand them up front.
So! A dually is in order. You then can put some of the heavy items in the truck to offset the low CC of the trailer. And you need it for the pin weight anyway.
BTW the six sides are what pushed the dry weight much higher than our Big Horn. Any salesman that says a 250/2500 can tow a six slide trailer is in the wrong job.
