My .02 Aluminum trailers are great if used in the salt belt or alot during winter. Otherwise the additional cost doesn't outweigh the benefit of being a little lighter.
Cargo trailers sell for a premium most places. Take your time and do some shopping.
I'll recommend MTI brand trailers. They're "average" quality. Not Aluma/Triton/Logan trailers, but the one I bought was well constructed and very good price. By comparison, the trailer you posted 8.5x16 basic white box trailer is the same price as a 7x29 inline all aluminum MTI with front ramp door (snowmachine trailer).
Also, if you get the right dealer, you can order the trailer YOU want and it doesn't cost anymore for the same features.
Didn't know this til I ended up buying a MTI trailer brand new a couple years ago.
Just a suggestion.
