Welcome to the forums. I have a 1984 Avion 30P that I bought in October. I haven't had time to really get in her to "make her mine", but I think they're great trailers too. The room in them is a lot more spacious than an AS (I've had several & still have a little one). I pulled mine from SE Ohio to NW Indiana and can honestly say I found no difference between it & the 31' Sovereign
I have pulled for quite a few years. The first thing I did was check all the systems. I've learned through the years to get the interior up to snuff first & then work on what's needed on the exterior. You should also make sure the running gear (tires, brakes, brake away switch) is all in good operating condition before you take it out. This forum has a LOT to offer--I wish there was an Avion forum that is as user-friendly as this one!
