I can answer from experience, we have a new 27RLS with Elite Pkg, Thermal Pkg, Aluminum Wheels and the Fiberglass Sidewalls. The yellow sticker weight as built with propane is a little over 6900 lbs so with battery and our "stuff" we're at 7500 lbs and the tongue weight is 1050 lbs (weighed with a Sherline tongue weight scale). We have pulled it with our F-150 Ecoboost and on a smooth level highway it tows real nice. However, when the wind kicks up or there are bumps and undulations, the ride isn't so smooth. We only have a 1500 lb payload capacity, so with the wife, dog and some tools, we are at our limit. This combined with a short wheelbase and being outweighed by the trailer by 1700 lbs does not lead to the most comfortable towing experience. It can be done but I'm going to replace the F-150 with an F-250.
