Safety Recall

I have been reading for some time now, all the posts relating to tow vehicle mileage complaints and the various theories.  I read that in Canada the requirements were such that clearance lights were required and the lamps were on a spoiler.  The mileage discussion was relating to whether the spoiler would reduce camper drag.  The conclusions were, as far as I could tell, inconclusive.

Now, just yesterday I received a safety recall notice relating to the need to install clearance lights in order to meet Federal safety standards.  There is a reference to the spoiler but I can’t tell if that’s what will be added or not. 

I called the dealer and the representative could not tell me what will be done.  I am awaiting his call back after he checks with others.  Stay tuned.

I wonder if anyone else has had the recall work done and what it consists of.

Has anyone that you know of reported that the spoiler addition improved tow vehicle mileage?

It will be a missed opportunity if the manufacturer doen't take this as a chance to kill 2 birds with one stone by adding required lights and enginering a fix that also addresses the rear drag.  Maybe someone at Forest River reads these posts and will reply.  It could turn in to an advertising benefit to be able to say "re-engineered for better tow vehicle mileage". 

Great news.  Any little bit helps.  Question: is the spoiler the one we can expect to have put on as a result of the recall, or is it an after-market spoiler you found and installed?

I was afraid it might be only a holder and not functional or designed to reduce drag.  Eliminating drag is probably a dead horse, i.e., a problem that can't be solved.  All I can do is slow down a bit and hopefully climb above 10-11 mpg.
