If the mirrors don't sit in the exact right position there is a bit of fun with the mirrors , the Silverado Utes must have lower seats I suspect .
Overall the better vision you get is so much ahead of OEM plus a caravan mirror because of the blind spot mirror .
No trouble backing in tight car parks and can get to within 50mm of the trig hitch on the camper every time .
Because I've made my brackets completely out of steel I can pack out the tension spring with washers if vibrations become an issue , at the moment I think there about the same as the OEM mirrors as far as that goes .
Yes blind spot mirrors can be moved out as far as they go which leaves them sticking out but don't think it's a problem , passenger side won't fold back against the car if I hit something because of the snorkel and this could be an issue on tight tracks .
