I had one, non-adjustable, for my fifth wheel, attached it to the cargo rack on the back part of the crewcab. I did see slightly better mileage when towing but it was such a pain to put on and attach securely that I left it on while out touring when we were travelling, wiping out any potential gas savings. It did, however, move the 'bug line' way up to the top of the fiver, so some benefit there. I bought it used for $75 and sold it a few years later for $50.
Ya, mine is adjustable and can be laid flat when not in use. Yes, I too had very little big splatter on the front of the trailer. Which shows that it works. It was also way easier to clean the front after a trip.
