lance 2385 and 2009 Jeep GC

I have a Jeep Grand Cherokee with 7200 lb weight limit, a tow package and plan on getting a P3 break system installed and a weight/sway tow hitch. I feel the Lance 2385 being 28ft long may be too long for the Jeep. Anyone with any ideas. Otherwise am looking at the Outdoor black rock 19b. thank you in advance.
