For only $200 difference, having the stronger A frame tongue, bigger wheels and better tires, and a better axle is a no brainer in my opinion. If you’re going to go less might as well just get a cheap 4x8 harbor freight trailer to use until you step up your tow vehicle. There are bargains out there. I bought my trailer in late December from a long established local trailer dealership under brand new ownership. They were really anxious to move some inventory before the end of year and reduce a bank note going into winter. Enclosed trailers are nice, I used to pull a 20’ enclosed car hauler but you really fight the wind, even with a proper tow vehicle.
