Ugly Bob is an international traveller - as am I and we don't have the luxury of sitting at home to make our vehicle purchases.
He was just unlucky.
I bought our Airstream Cutter MH in CA sight unseen. Many years later we still have it and there have been no problems that I haven't been able to fix on the side of the road. Been from bottom of Mexico to the Arctic Sea and all points between.
F350 with Big foot camper bought sight unseen in South America. Did the job perfectly although we did have some brake and suspension problems.
OKA 4WD truck - bought sight unseen and it is still going strong.
Class motorhome - bought in Amsterdam. Did the job but was a bit of a pain so we took it back and got a refund
Iveco Daily 4x4. Bought sight unseen in South America knowing exactly what a bomb it was and paid the right price for it. WS only intended to last 6 months and it did everything asked of it. Decided to continue in south America which is why we bought the big foot.
So I perfectly understand the OPs situation and for me, sight unseen has worked well and saved us many thousands in wasted air fares and accommodation
