The smallest is 5x10' and it'll use all of it. The RTV is 59.8" wide and 119.3" long. That gives less than an inch around. I don't recall if those people were using ramps instead of the lift gate since the lift gate might hit the box. I would do thorough measurements on RTV and trailer before picking this size. If you changed things like tires, it may no longer fit.</P>
I like (and prefer) a 6x12'. It gives me a little room around all sides which makes it easier for loading, tieing down and adjusting length for tongue weight.</P>
What size trailer were you considering?</P>
