I got the curt hitch brand hitch on sale shipped for like $113.
My miles per kwh sucked.
About 2 to 2.5 miles per kwh.
I made my trailer.
It was a 4'x8' bolt together harbor freight trailer 3 revisions ago when I bought it in 2008 to pull behind my diesel suburban.
Now it's a 4'x8.5' fully welded frame, rides on a 2,200lb brake axle with 12 inch steel belted radial load range E alloy wheels and Aluminum diamond plate deck.
I spent about $500 just on the brake axle, springs and wheels.
Is going to get you.
