Pro-line are decent trailers. I personally am sponsored by H&H Trailers out of Iowa and I absolutely love this thing. No Bullshit here...if it wasn't any good I would say so.
I have a 28 ft tag, smoothside, onan generator, 50 amp elec service, full light and ac package, E-trac in the floor, and the entire frame of the trailer is sprayed with a thick coat of linex. The only thing I would change on mine is I would put a elec jack up front, a winch in the floor, and I would try to build one out of alluminum. My motorhome and F-250 pull it great.
If your interested in a hook up, I can set you up with the right person. Let me know.
