Tully, what is the legal limit in your state of residence. That's the standard you will be judged by on Interstate travel. Exception being California. I won't even guess what can happen out there. I have gone over 75 ft. on several rigs in the past and was only stopped once down in Mississippi. He just wanted to look at the rig (motorhome, Jeep and Hobie Cat) and turned me loose without even a warning citation. If you prefer the 24 ft. trailer, buy it. I really don't think you are going to have any problems.
