I have ordered a RT-S. I have a 8X16 ranch trailer. I don't have ramp, just small ramps to load my Kubota. I am thinking of having one built at local trailer shop. One that folds up...I guess I will have to take the Spyder to the shop and make sure they make one that will allow me to drive the machine up on the trailer without hitting the bottom....I will use on my Gold Wing trike as well....not sure how long that ramp will need to be....may be heavy to lift...oh well.
