I did have strong side winds that turned into a head wind the whole way home. Radio was saying gusts up to 30 mph. A couple hills but nothing huge. There is one on the way to a spot we like to camp and it is steep with lots of curves. I am going to get the rear suspension improvements added and try that hill out soon as a test. I think if I have to white knuckle it up that mountain then I'll go get a bigger truck. I like that quote and probably good words to live by!During your 180 mile test run was there any high side winds or much curvy/hilly 2 lane highways encountered? That's where a lack of "not enough truck" will rear it's ugly head. Driving a pick up truck not up to the requirements of a large hard side camper in high winds WILL get your attention as will narrow 2 lane highways that have heavy truck traffic, curves and hills, not my idea of fun. Never be so married to a truck that is not a proper choice for the job at hand to get the correct truck you truly need.
As my dad use to say "it's always better to have too much truck than not enough truck". In 1961 when I was about 5 years old he bought a slide in 8' hard side camper which in that time was a big camper not to mention a very rare thing to see. At the time he bought the camper we had a '58 Chevy half ton step side PU with a inline 6 cyl. motor. It got the job done but barely, it was underpowered and swayed with the weight of the camper which didn't have all the bells and whistles today's campers have. He upgraded to a '65 Ford 3/4 ton with a V-8 which made all the difference in hauling that camper around safely.
