It's all (uminum) good...
Mines aluminum its awesome old All speed that used to be built up in Parks ville. Very well built trailer.No problems and I travel on some rough roads sometimes. Keep in mind my boat is lighter 16.5 DE..... Honestly only issues I ever had is with everything else axles/bearings. And I would rather not bore you with the engineering related stuff so i wont comment......... Personally stress cracks can form in either material....High Five

OMG - stress cracks???

Stay out of planes and aluminum boats???

Aluminum fuel tanks???

Take those aluminum commercial trailers off the road??? Get those damned aluminum alloy wheels off???
An aluminum or galvanized trailer debate is similar to the bunks or rollers discussion - both will work just fine. Personal preference prevails.
Aluminum trailers can be every bit as good as galvanized steel (You get what you pay for. Did you get that "super deal" on a
Nextrail or
Magic Tilt- then complained of your trouble with "Florida trailers"? You could have bought a
Loadmaster.), although they are usually more expensive to purchase. Minimal corrosion (galvanized=zinc anodic corrosion in salt-water), a lighter tow so less fuel, and a lighter tow package - maybe your 1/2 ton will now do the job. Buy a
well-built trailer from Florida or Washington State or even Canada. U.S. manufacturers must comply and be registered with the National Highway Traffic Safety Administration (NHTSA). Many manufacturer's offer both galvanized and aluminum (eg. EZ-Loader). The manufacturer has done the engineering required to prove it's roadworthy, so you're all good. Trailers built in or imported into Canada must comply with the Canada Motor Vehicle Safety Standards to get a V.I.N.
Trailer trouble's start when they are poorly maintained and / or overloaded. Manufacturers will often supply a boat/trailer package with the trailer straining at capacity. Now add a kicker, fuel, water, beer... - you get the idea. I have a 7000# GVWR rated tandem trailer (aluminum) rolling at about 5500 pounds. With full tanks it's up to 6000#. I'd be legal with a 6000# trailer but not too smart - especially on that road to Poett Nook.
