Which years of Outdoors RV's had corrugated siding?

Good points from all, thanks for the insight.

I haven't owned a fiberglass sided RV yet, but that will likely change with my next one. The aluminum siding on my 2004 trailer has held up well except as pointed out that it is susceptible to dents and punctures. I've used aluminum tape on a couple stab wounds from branches. My trailer lives outside year round and sealing the windows and edges has not been a burden. I did it once when the trailer was new, then again after about 5 years. The decals are peeling here and there, and the door is a little yellowed, but overall it's sound. Now, in its 18th year, It needs it again around the front running lights, but the rest still looks pretty good. I expect with a little TLC, a fiberglass RV would perform similarly. I believe the key is immediate preventive maintenance upon purchase. JMHO

My previous TT was corrugated aluminum sided. Agree with all the points that carringb made and will add that keeping it clean was a nightmare. The siding oxidizes and the only thing that removed it was Meguires Cleaner wax. The wax would wear off and oxidation would begin again.

Maybe look at units a few years old - at least to see how they are holding up.

They offered the Black Trail with corrugate siding through 2014 I think.

Corrugated aluminum is not lower maintenance. No way would I ever consider getting another trailer with it. Our Jayco had it. My ORV doesn't (my Weekend Warrior was also fiberglass).

The aluminum siding is prone to dents, holes, and tears when dragging it off-road. Caulking doesn't last neat as long because there's so much more body movement. The body isn't near as stiff. The Jayco had to have its curbside wall rebuilt because the framing failed. Composite structures are just stronger and more durable.

The stuff I've put my ORV through is pretty impressive. I don't think ORV has cut any corners design-wise recently, but they've likely has more issues like everybody as they try to crank out as many as possible with a reduced labor-force.
