You made several points in your post, @Mudman1
. Allow me to address each of them, and please do not take them as a personal attack, because they are not intended as such.
None of us know the backgrounds of other members.
i didn't claim to, and respectfully, my statement did not require knowing your background in order to make it.
I can tell you first hand that I would rather work with and own aluminum over steel.
your preference notwithstanding, as a general rule, due to its higher malleability rate, by its very nature, aluminum tends to be a more difficult alloy to work with. not impossible, or no one would do it, but my statement was not incorrect.
I ran a custom Buckstop bumper on my Ram 2500 Cummins for over 60,000 miles without a single issue. The coating stayed on the whole time. I lived in D.C. then northern MN, so it was exposed to salt and all of the elements. It also held a massive Warn PowerPlantHD winch.
Respectfully, you are one experience among millions. My statement about coatings not adhering as well did not mean that they fall off 100% of the time. Search for 2005-2014 Ford mustang hood paint issues. Due to Ford's switch from fiberglass to aluminum, their hoods to this day have issues with paint not adhering to the material, and that is a characteristic of the material, not just in their application process. not all aluminum components will exhibit this behavior, and not even most of them will. but they have a higher likelihood of doing so than steel.
going back to their higher malleability rate than steel, this is why you normally only see aluminum in non-structural parts on a car, ie. hoods, deck lids, lift gates, etc. i personally would never want a component designed for structural safety or one designed for off-road recovery to be made out of aluminum. fun fact, the KL's OEM bumper is aluminum for weight saving purposes. however, it is designed to be a break-away, impact-absorbing component and replaceable, so its malleability is not an issue, even desired, in cases involving a head-on impact. however, i feel better knowing that my RRO bumper is made from welded steel, and should i need to push/pull with it, it will be strong enough to hold up to the task. i certainly would not want to put a winch in an aluminum bumper and risk deforming it with a hard pull.
I also designed a custom aluminum trailer I tow behind my KL, and would never trade it for steel.
Apples and oranges. Aluminum is much lighter than steel (which i believe is a substantial part of your argument above) which is highly desirable for trailers. You want any towed object to have the best balance between lightweight and strength, and aluminum in this case works best. i would imagine, however i do not know for sure, that the frame of your trailer is still steel, as is the axles, axle shafts, and other load-bearing components.
This is my opinion, and we shall see what the market decides to bring to consumers, if it brings anything at all.
And i respect that, and i'm not saying your opinion is wrong, i'm simply pointing out why i disagree
