I'm not sure why anyone would take a 3+ hour drive without confirming that they'd have the part you need - unless of course they enjoy a long car ride.
To be fair though, there are a number of large RV dealers within mile of there including La Mesa, Freedom RV and of course the ever "popular" Camping World.
Our main mission that day was to take Mrs Eagle's sewing machine in to be repaired. Lazydays was a side trip. Saw La Mesa across the road but perhaps wrongly I assumed they would be the same as Lazydays.
We did stop at nearby Camping World, but they didn't have what I needed in the right color. Both LD and CW recommended Sandy's RV, a small RV parts store a few miles away that supposedly carried hard to find RV parts, but they didn't have it either.
What I was looking for was the 1" wide vinyl trim insert used on many of the Winnebago motorhomes I've seen for years. The rigs, like ours, were tan in color (I think Winnebago calls it Champaign) and the trim strips matched.
Last fall when we were returning from our trip to Indiana and passing through El Paso, one of those strips that runs from the top of the front cap all the way around and down next to the entry door, came loose and was flapping in the wind. After stopping to cut the offending strip off, we continued on home. Local sources carried several colors of the strips but not in tan. Black, white, and a couple off-whites, but no tan. They couldn't even special order it.
Back to Sandy's RV: the clerk there said she recently had an opportunity to talk with a rep from one of the major RV parts suppliers in the country. He asked her what his company could do to help her business increase the business she could do with his. She said she knew his company also sells to Amazon and that Amazon's prices almost always undercut the "little guys" and asked him what he could do about that. He didn't have an answer.
And finally, about the tan vinyl stripping that apparently is no longer available: the lady at Sandy's suggested going with a contrasting color like black. At first, I didn't like the idea, but as time goes on, I'm warming up to it.
