I have never heard anything bad about the CS other than getting a call returned when they are short staffed. I don't have Cell service at my house I have to drive 5 miles to hit the Tower so... If you're mounting it in a trailer why not add an extension handle to the intake seems like that could possibly solve the problem. Were they aware of it's final resting place before you ordered it? Did you show them the trailer layout and where the pit was to be located? That should have sent off a few bells or did you just assume it was located on the door? That do make a difference.
