I have the Airlift also on my 2014 F-250, long bed crew cab 4x4 and have zero problems. Was going to get the Firestone but our local truck accessories store had the Airlift in stock. Having looked into both in detail, even talking to people who had either, there isn't a lot of difference in the two. No compressor and I'm running a single inlet for both bags. I think you'd be ok with either.
