I had a good Toyota Tundra 2012 pulled a 10,000 lb camper all over the west on two trips.
Hate to admit it, but 1/2 ton truck should not be pulling big campers.
This truck here was the best thing that I had done. Love the mileage, love the handling and all the delusional cost comparisons that I heard, are just that, delusional. If you have a big camper, get a big truck, unless you drive your Rv within a 100 miles and stay close to home, don't go 1/2 ton.
