Does a lower profile tow better? NOT a mileage Question

Probably not, you're going to be payload limited, not horsepower with the EB. 6200 dry will be at least 7,000 loaded and probably ~900lb of tongue weight, add another 100 for the weight distribution hitch and you're at 1,000lb which only leaves 400lb for people and cargo, probably not enough. Your initial though of <5500 is probably a better match to your TV.
