My Voltage was full of problems for the first six months of ownership; we were hating it. Once I fixed the problems it's been a reliable trailer.
Almost all trailers by all manufacturers are built quickly without any quality control. The line workers are paid by how many units they can work on so they're not interested in doing it right, only fast.
One example is the worker installing the middle, fully-ducted a/c was in too much of a hurry to clean out the sawdust before applying sealing tape. Of course the tape didn't stick to anything and all the cold air vanished into the ceiling. Another rushed job was the builder didn't use wide enuf plywood under our queen bed so that about 8 inches on the side of the mattress had no supporting plywood under it.
You take your chances with any RV you buy.
