Re: Renting a trailer for a 2501L
U-Hauls car haulers, are open center floors. They might work depending on the track width of the machine. Those are only like $60-$70/day or so. Tie down/load securement points, might be a little difficult to do correctly, since they use a proprietary built in system.
U-Hauls open utility trailers (they all have sides), have tail gates that are narrower than the width of the actual trailer floor. I asked why this was, and it's because people would rent them since they are cheaper than the car haulers, and then load cars on them. Their fix was to make the tail gate narrow.
When I bought my B8200, I used an enclosed double door U-Haul trailer, and some car ramps to drive it into the trailer.
Worked pretty good, not ideal, but it worked. No ROPS on that machine BTW.
Couple "First Place Rentals" (same type of place the D2Cat mentioned) around, that rent trailers of varying capacities, for $100/day or so.
