Rear fiberglass cap

Figured they all come with a front and rear cap...didn't know you could order a rear cap:h If the 5er has a "finished back end with seams in it, that is the rear end cap.....or maybe I'm completely misunderstanding your question.

I've never considered a cap to be optional either. To op, are you referring to the (usually) fiberglass front exterior or back exterior wall? Could be aluminum too.

The molded rear cap might provide better aerodynamics but I would think the benefits would be negligible. They do look nicer.

What is the alternative to an aerodynamic, nice looking end cap? You mean you can order more than one "optional rear end cap"? It's GOT to have some kind of rear end cap on it, never seen a 5er with out one...even aluminum has the back end.

Any square corner hurts mileage, front or rear. Is it measurable? One would need a wind tunnel and two rigs to test. However we like our rear cap and think those that do not have them look unfinished. Chris

I should have clarified...it comes standard with the flat rear that is the same material as the sides. There is an option for a fiberglass contoured rear cap. I'm wondering if there are benefits for this option beyond good looks.

Guess that is more your call....if money is going to be the difference, get the flat rear. I like the looks of a contoured, little more aerodynamic rear end cap....I believe it may help a "tad" with mpg when towing, but either way, would probably not be that much difference.

never heard of that as an option before....out of curiosity how
much does it cost?

1. Never heard of Columbus. Who makes it?

2. It will probably take about 20 years to recover any added cost if you are going to count on improved MPG to pay for it.
