Help deciding. New travle trailer.

The engine is not the problem, it's payload and short wheelbase that will give you the most issues, particularly with the longer units. Getting info from those that don't tow with the exact same set-up is fruitless, no doubt all three will be felt behind you, although the Sonic to a lesser degree. Possibly it wouldn't be too bad if you were just staying within a few hours of home but the trip you have planned will tax your TV heavily and there will be adverse weather conditions to deal with from time to time. High winds and interstate speeds don't bode well for a short wheelbase vehicle towing a long TT, a high quality WD/SC hitch will help but it can't overcome all the physics involved towing under those conditions.
