I dont know were you got your info but few people around this sub forum will recommend an AL trailer.
As we have all pointed out in the past....
if you chose to go with the above listed.... a Featherlite 3110... it weighs in at a generous 1350 lbs and lists for $6000 new (source
Featherlite 2013 3110-0014 )
by comparison, a brand name (big tex in this example
Big Tex Trailers 50LA Tandem Axle Utility - Big Tex Trailers)
16' landscape trailer weighs in at a wopping 1535lbs and costs about 1/3 the price.
so you could loose 200lbs of capacity, pay 60% less and still have a trailer that is more than capable of pulling around your lawnmow ..er JD "tractor"
PS id ballpark a fully loaded 1025r TLB at no more than 2600 lbs.
