Class C Vortec V-8 towing Ford Fusion.

I have pulled trailers and equipment since I was a young boy working on the farm but do not claim to be an expert, just someone with a lot of experience and never having any issues. IMO, you do not have the tongue weight issue to be concerned about but you have more weigh to pull and that weigh will also push you. You may notice the additional weight while maneuvering winding roads and you will definitely notice it during braking. The drive train of your rig, engine, transmission, brakes, differentials, frame and tow hitch, are designed to pull and tow a stated amount of weight and the vehicle you want to pull exceeds that weight. My Super C is designed to tow much heavier weights than your RV and while flat towing my Jeep Wrangler Unlimited I can feel the Jeep push while driving curvy roads so much so that on a trip last summer coming out of Emminence ,MO on HWY 19, I disconnected the tow bar and had my girl friend drive the Jeep until we were farther north and out of the Mark Twain Forest area. My chassis is an F550 diesel 4 wheel drive. Your rig is quite a bit smaller than mine. I hope this helps. Merry Christmas
