Thanks. I sent an email to both companies asking them the same question. Trailair responded right away with the answer. It's been 2 days and no answer from Fifth Airborne. This, and what I've read in another thread about Airbornes lack of responsiveness, I will go with TrailAir.
Again, thanks from your answers.
