I have the Amp steps and last month I went to Colorado. I made a trip up in the mountains and went across a creek that was flowing high that day and the water went probably 2 inches up my doors. In about a couple of weeks both motors went out and I have been trying to get their warranty guy to send me 2 more and it's been going on a month now. He just can't get it right and keeps asking for the same information about my invoice with pictures and a proof of tests they want you to run before making a decision on sending out replacement parts. I bought them last year and they have a 5-year warranty. So,,,,, would I buy them again? I have had them on other vehicles before and no troubles, but I don't think they like being immersed completely under water. So, I would give this information some thought before I bought Amp's products.
