OP....have you actually backed under the Reflection and checked the height with the pin weight on your hitch. I recently purchased a 30' Reflection 150 Series 5th wheel and it worked fine with my Ram 2500 2WD.
My previous trailer had to be lifted and converted to 16" wheels, but I was pleased to find the new Reflection set level and provided great bed clearance with the 15" factory wheels. Of course I did immediately change the tires out.
I do realize your truck is a 4WD so you may have to take measures to get the trailer level, but give it a try.
P.S. some of the above posts indicate your OP was not read before replying.
