What size trailor do I need for one 36" WB, one 48" WB, and a 60" ZTR. Assuming I put the WB's in sideways, will they all fit on a 16' trailor. Reason being, I have a 14' trailor currently that is sufficient for my two WB's, but am looking to upgrade and include a ZTR. Gonna need a trailor as a result. I'm almost certain an 18' trailor will fit in my garage, but am leaning more towards a 16'. Thanks, Harry.
