Car Haul Trailer, Steel vs Aluminum, Which Would You Choose?

alum took over the horse trailer market years back, BUT they are heavy even if alum! ha open car trailer doesn't weight squat! rust is issue with steel horse/stock trailers so alum is the choosen material IF a person wants to pay the price.
open car trailer, steel for sure IMO, I have had both wood and steel floors. some people claim the car will slid around on the steel treadplate floor but I never had the problem. I like treated wood floor and pour used motor oil over it o nce a year... works for me. I pull with a ton truck, but I feel brakes in one axle is fine.
I like 18 ft. 102 in wide, dove trail, if having it custom made I would go with standard FRAME AND HEAVIER AXLES, 6 lug rims. GOOD trailer spec tires. just me.
yep gooseneck pull soooo much better like he said, but cost more for sure.
