Sorry for the long delay. I don't see the profile comments when I check the forums on my phone. We no longer have the long trailer, but we towed it (73 ft total) for a couple of years without issue from anyone.
Do you know what your overall length is? With my enclosed trailer behind my 44B Anthem my overall length is about 73' so I always use the shorter open trailer for trips to California. Just curious about your overall length.
