If you have looked through this forum thread and are interested in purchasing a compact aluminum trailer that can hold an RV-12, now (August 2023) is a good time to do it. I am definitely trying to get one made and I have gotten PM's from two other people who are interested. The manufacturer would prefer to build 3 or 4 instead of doing just one "line buster" that screws up their factory production. I am expecting high-quality but it will cost more than $30K plus fit-out. This is for a trailer suitable for long cross-country towing not primary use as portable hanger. Send me a PM.
It seems like something Van's would be interested for their demonstrations after seeing that FLiteTest collaboration video at Flight Fest. I was embarrassed for them when I saw that this supposedly 'trailerable' design was dragged out into a field on two separate flatbeds and a pair of 1 ton trucks.
