I
got tired of trying to move the trailer around on the small tongue wheel, so
$50 later I have a trailer dolly! It only came with a 1 7/8" ball,
but I have never had a problem using it in the driveway with my 2"
coupler on the Santa Fe. It has a 600 pound tongue weight and 12'' x 4''
pneumatic knobby tires which move our pop up very well.
