Quality is abysmal. The manufacturers kick them out the door as quick as they can without anyone even cleaning up the leftover sawdust or checking to make sure things work. We, the owners, are the ones that must discover the defects. It took me a year to get the bugs worked out of my Voltage and I chalk them up to lousy workmanship at the factory.
The plywood under our bed didn't reach the side of the bed (8 inches too short) meaning mattress and the person sleeping there drooped over the side. I fixed it myself. Others say the factory denied it was a problem.
The ductwork under the main air conditioner (fully-ducted) was not properly cleaned of saw dust and the aluminum tape used to seal the area rolled itself up into a ball. The cold air went into the ceiling rather than into the ducts to be distributed properly. I fixed this myself, it was an easy fix. Again, no quality control.
The Schwintek slide system broke and needed to be repaired. It hadn't been installed correctly.
If I had it to do again I'd buy a trailer a year or two old that has had the bugs worked out. I'll never again buy new.
One other point about trailers - there are no detailed owners manuals. The one I got is for every trailer made by the company too generic to be of any use. There are no wiring diagrams, no plumbing diagrams. There is nothing to tell us how things work, or are supposed to work. The manuals we get from the component manufacturers (a/c, water heater, tv's etc) are acceptable but if you want to know how your tv coax is wired forget it, diagram doesn't exist. We are left to figure things out ourselves.
On the positive side once I got the bugs worked out the trailer has been very good.
