There is no question that AF doesn't concern themselves with weight as much as others. They even indicate that in one of their videos by saying they will not sacrifice build quailty for the sake of reducing weight. I found that their build quailty reflects that philosophy. When I was looking 3 years ago to buy I narrowed the search down to my two closest dealers, Lance and AF. I became sold on the overall quality and fit and finish after looking at AF. Granted, you have to have the right size truck for all the AF units, but if you do you will not be disappointed. I never looked real close at the EC so I cant make any judgement on those. Had their been a closer dealer I sure would of considered it.
