I wish you better luck on the warranty than I had. I had the 1000s, after about a year, one developed a leak. Didn't blow, but wouldn't hold any air. Tested the airline, tested the valve, all good there, so it was definitely the bag.
After going back and forth for over a week via email with them asking for various bits of information that I had already provided in my warranty registration, they asked me to call them to discuss the problem. If they had asked me to call them to begin with, cool, but there was no point in over a week (typically with two-day delayed responses on their end) of discussion only to have me call them. The way their customer service sounded was something along the lines of "this email thing is to hard."
I was probably a bit petty, but I was already annoyed when they asked me to call. If their point was to try and get me to stop bothering them over a warranty on a pair of sub-$100 air bags, it worked. I threw my 1000s away. However, they also lost a customer that will probably not buy their stuff again.
I bought the Timbergroves. So far, they work quite well, and I can inflate them even when the truck is loaded. With the 1000s, if you did it after loading, it did not lift the truck up to reduce the squat.
