Maybe not helpful since we have a Ford srw with a long bed but it tows our Pinnacle so well. The ride is really good and we've been to the Colorado Rockies a several times with it. I have no problem keeping up with traffic. Our previous two trucks were duals which are the same length but the srw just drives easier since I don't have to account for the wide hips.
Your NP is basically the same length as our Pinnacle but not sure about the weight comparisons. It's GVWR is 15,500. Fully loaded for a month long trip it weighed 14,700 with 3120 hitch weight. When we bought our truck I really wanted a short bed but what I ran into was the yellow sticker load capacities. A short bed Ford F350 had around 3200 to 3300 pound load capacities with a GVWR of 11,500. That didn't leave much room for us and whatever we carry. GM's were similar. I didn't look at Ram. Configuring a Ford long correctly upped the GVWR to 12,400 and the capacity of our Ford is 4054.
GM has since upped their 3500 short beds to 12,100 so that would give more capacity. Again, not sure about Ram. I'm not a member of the weight police, ever. Just an FYI of what I encountered.
