My wife and i purchased (and have since sold) a 2009 17ft Aliner A-Frame
. One thing we found out during our research is that it is common for this style of folding trailer to have instances of water damage when folded for long periods of time. Each owner we spoke with or read about said that parking the A-Frame trailer in the _up_ position was best for longevity. We parked ours in the up position at our old stick built house for two years and had no issues.
As others in this thread have suggested, often times the weights of fiberglass trailers are equal to or less than similarly sized stick built trailers. In our case, our 17ft A-Liner empty was ~2300lbs (it had a 30 gallon water tank we never filled before getting to camp.) and a ~400lb tongue weight
. Our Parkliner
is 15ft, but ohhhh so much roomier ! . .and 2400lbs with its 15 gallon water tank full and 230lb tongue weight
at scales. The biggest issue for us with the A-Liner's up/down thingy was we just got tired of it! And pulling the 7wide A-Liner verses our 6.5wide Egg is night/day. I'd take the egg any day!
Anyhooo, best wishes on your search for a rig for you two.
