I have several trailers... all get used for many things... have one of the lawn mower trailers, it's handy for the mower for little things... next biggest is one made out of the bed of a Ford Ranger, bought for cheap and haven't used it much partially because it has a flat tire... next is a Harbor Freight 4x8 trailer that I've had for ~6 years, it's a work horse, I put 2' plywood sides on it and have hauled my 3 wheeler (Honda 350X) to the dunes a couple times, hauled RC airplanes around in it (made a lid for it so it was enclosed) and had it full to the top with bark dust for the yard. Also have a 7x12 deck trailer that used to be a travel trailer that I have a whole $200ish in, it's way overkill since it has brakes (not wired in) but I haven't put more than 1000lb on it I don't think, and the other trailer has two mobile home axles and I think a 6x12' deck and sides...
All get used for anything and everything... the HFT trailer is currently full of apple tree trimmings, the single axle flat trailer is full of grape plants since my burn pile is super full right now and the ground is too saturated for the tractor to drive over to it without making a mess to press it down, burn season doesn't open til March...
