My two cents;
I was getting some repairs done at a So Cal dealer for two days, so I had a lot of walking around time on the lot.
I did a little survey. I looked at approx. 20 Heartland Bighorns, Landmarks and Sundances.
There is a direct corellation between the manufacture date on the side of the trailer and the amount of rust/corrosion on the chassis of these rigs.
Jan=moderate.April=slight. May,June=none, pristine underneath.
After a while, I could almost guess the approx. mfg. date by looking underneath at the chassis.
Some of it doesn't look like a one time through the salt type corrosion. It's more like, these chassis were, maybe laying under a pile of snow somewhere for quite a while.
Maybe there could be an effort made to protect these components before the build, both at Lippert and HL.
Also, how about a shrink wrap of the chassis, as much as possible, to insure the rig arrives in as much of a "like new" condition as possible? Like auto mfgrs do.
Bob, I know what you are saying about the structural integrity not being an issue. It's more about the psychology of paying 60k for a rig and then immediatley having to go around doing touch-ups everywhere.
