Trailer Size Assistance Needed
 

I am having some trouble deciding what size trailer to get for our first set of ATV's. We need a trailer that will fit an 02 400ex, 02 Rancher 350, and a 01 Scrambler 50cc. Will the 400ex and Rancher fit sideways(perpendicular to the length of the trailer) in a standard 6x12ft trailer or do I need to go up to an 83x12. I was hoping to get them in a standard 6x12 with rear load only but I'm not sure that is going to work. Any advice would be great, I am on a budget so the smaller the trailer the cheaper the price which is why I'm trying to find the tightest fit. Thanks in advance for all of you help.
