Dmace, i was just estimating on the weight, never had it weighed for that trip. I think it has a 7500 gwr, and i don't recall the model off hand. Since you're familiar with Proline, you probably know it is all aluminum. This one has a translucent roof too.
Yes i may have been overloaded! But i made the trip of over 5000miles never exceeding 55-60mph and never had any issues, even with all the many miles of gravel roads etc. Closest calls were an accident that occurred RIGHT in front of me on the freeway, and once about 3/4 of the way through my trip finding my hitch ball's nut almost worked its way off.
