I have a 2500hd with the same engine; I've pulled my cyclone with it a couple of times and it wasn't really do able (voltage's are the same size)
our previous 5th wheel was right around 12k loaded; it was well sized for the 2500hd
regarding the quality issues
all the standard rv manufacturers will have some quality issues; voltage, cyclone, raptor all have pro's and con's but I wouldn't categorically assert any of them are quality deficient
I walked through all the brands, we landed on cyclone and have been very pleased with the final product.
