I have a 35ft dual tandem , a 16 ft tandem, a 6.5x10ft and 5x8ft single wheel trailers. They all have their purposes, the 2 smaller trailers are used alot for transporting my 2 ATV's, Kubota RTV900,and 2 Polaris Rangers. The neat thing about the 5x8 is it is not to big for the ATV's to haul around. I just picked up the 6.5x10 to have a little more room.A Ranger take up every inch of the smaller trailer.But all of these pull very well loaded or unloaded. I would opt for a trailer that is a little bigger than you need at the moment. One can always find ways of filling them up on a hunting trip.

here's my smallest....
PS...I have treated wood floors on trailers, expanded metal will also work but allow dirt,mud ect to come up through it. Metal floor/checker plate is good and longlasting but gets quite slippery when wet.On my 2 small single whell trailers they are equipped with a tilting bed so driving on and off isnt a problem, no ramps are needed. my $.02
