Sometimes they do surprise you.
My transfer tank/toolbox combo I had installed on my new flatbed F350 in 2017 started leaking when I filled it up. It would leak until I pumped out 30 gallons or so...
Made a mess. It was getting old. No way to find the leak, it was coming from somewhere I couldn't see on the mounted tank.
Started looking online, and saw the new tank combo was $1500 now.... Aluminum.
But while there on the website, I looked up the warranty. Well! "Lifetime Limited Warranty".
Hmm... we'll see. I called and got customer service. He said it was probably a weak weld, and gave me instructions to take photos and send my receipt, etc.
Just got my brand new tank this past week. No charge. No shipping charge either.
I'll keep buying UWS toolbox products for sure!
