I think the short wheel base of our truck may have something to do with it, other than that we have the same setup and the 5.7L to boot
...but it was extremely windy and gusty so I'm sure it would be fine in regular conditions.
We decided to purchase the Hensley anyway cause we plan to do lots of camping in the next several years with this setup and this will keep us from worrying about any weather conditions along the way.
One thing about Rockwood, ours is a 2011 but we purchased it used and I don't know if the previous owner pushed the slideout too far or too many times but the gears in the slideout motor/gear drive stripped on us the second time we opened it and had to take it out to replace them. It's an easy job and the gears where free from the manufacturer so no big deal for us but I just thought I'd mention it. Other than that we LOVE our trailer
Have a Happy New Year and a great camping season.
