Fifth wheel mileage question

I agree with the person who said heavier FWs often equate to quality. I also agree with the two that said, don't sweat about the mileage; pick the floor plan that works best for you. On that, I have to add that after four travel trailers and knowing what we liked and didn't when we started looking for an FW, we had every salesperson bring the slides in so we could see what that felt like as far as walking around when we stopped at a rest stop or had to spend the night in it that way at an overnight stop. That was an eye-opener. In our FW, we can access all kitchen appliances, the commode, and can sleep in it, all with the slides in. Good luck in your decision.
