Of the three, I like the Voltage the best, but I didn't end up buying it either so my opinion doesn't really count. When you say your are getting an F350, will it be a dually? The reason I ask is my Fuzion is smaller and lighter than all of those and I consider it to be an absolute maximum load for the SRW F350. Not to get all weight police on you, but there is no way to be absolutely legal on weights with a SRW on any of those three. I am within the RAWR of my 350, but over on GVWR by about 700 lbs. That is with the trailer loaded to about 1,000 less than its rated capacity.
