Sportsmobile actually uses them as their supplier for all their conversions (you can buy straight from Aluminess as well). As many options for the van, Aluminess bumpers and accessories are one of them they offer. Our van came outfitted with the front and rear bumpers from SMB. They're great cause the weight and durability. 85 lbs is about what one of our bumpers weigh in at. When you're already talking about a 10,000 pound rig, every weight savings you can make is important. Our bumpers are 5 years old and still look new. The powder coating has not flaked, chipped or faded. The swing outs on the back are still functioning as they did on day one. They don't rattle and they swing freely. I've never heard of anyone complaining about the products they make not holding up to the rugged elements we travel in. We don't do any crazy rockcrawling so i can't express my opinion on that.. but for overland use they're products work flawlessly. One other thing i'd like to point out, is that Dave will work with you on creating options to fit your needs. If there's something you'd like on the swing out, that they don't have or something you'd like to change/added.. many times it's no problem for them to do that for you. I don't mean to sound like a commercial.. but i endorse them 100%.
