3.73 to 4.10 gear change

My limited slip is going bad. It chadders rounding corners when towing my 8000# travel trailer. Changed rear end grease with additive, and no change in the way it acts. So, I think it is time to go into it. While reworking the limited slip, I was considering changing the gears to 4.10. I mostly tow with my Excursion. It weighs around 8000# and has a near verticle front nose area. Since 90% of my driving is towing trailers, I would like to have more power while in the mountains. What are the cons of making this change? I tow around 60 mph and know rpm will be up around 200 rpm. I know it will hurt my running without trailer mileage. But I think it would help my towing mileage. Let me know your thoughts.

If I spent 90% of my time towing an 8,000 lb trailer at 60 MPH, I'd put a 4.88 in it.
