Towing question

Don't know what the rear gears are for sure but the guy I bought from says 4.10. Would I be able to tow 4,000lbs comfortably in mild to medium hilly terrain? Thanks

You don't want wind resistance. Remember that the drag increases by the speed squared, so the faster you go the more it increases exponentially.

Better off with more weight but lower.

Said differently, I get better fuel economy with my open trailer, loaded, than I do with my enclosed trailer empty.
