When we went to order our new Landmark, we also checked out ExploreUSA in Denton, and I was also unimpressed. They tried to talk me out of a Landmark and into a Carriage Carri-Lite.
We ended up ordering our Landmark from Sherrard RV in Colbert Oklahoma. Very knowledgable and friendly salespeople and, since they also own the adjoining KOA campground, when you go to pickup your new trailer, they put you up for a couple days in the campground and assign a service tech to your trailer and you can try it out right there and get anything fixed before you take it home.
Also, it is not toofar a drive from the Dallas area, straight up 75.
I would highly reccommend Sherrard RV (soon to be called RV Station) in Colbert Oklahoma.
Our Landmark Augusta is due off the assembly line on January 20th. We can hardly wait to get it.
