I really HATE when people post about products and have no idea what they are talking about. I have had 4 Tonno pro covers. I have also had one trifecta cover. The trifecta broke twice at the hinges. Now on to the pro cover.Probably not many if any, if you did any searches here.
Basically, it would be hard to compare them as to how well they are made unless you can see them side by side.
Can the basic trifolder be removed in a minute? Does it only weigh about 15 lbs?
This is the case with the Extang Trifecta.
How water resistant is it? Most all covers leak a little, usually near the front and only dribbles. Nothing that would seriously get the bed wet.
Great prices and they 'look' OK. Just some details missing like the experiences of owners here on the forum that collectively own just about every brand out there.
If you read enough threads you will. Not saying it is a bad cover, in fact it is one of the most popular ones around here, and I understand there have been more improvements.Spend a little more and consider Bak. I've heard nothing but good things about this tonno.
