Now that we're retired and have all those projects to do...
Home Depot is clearancing their 4x6 utility trailers for $399, marked down from $549. This may not be available in all stores, so your mileage may vary.
Its a 1 ton trailer, most parts rated for more than that, with a drop down ramp and a small 'fence' around the perimeter. It has the "pockets" to put in hardware to build-your-own wood sides. Class 2 hitch. Pretty heavy duty for what it is. Almost any vehicle can be equipped with a class 2 hitch, and unless you're going to put a ton of dirt or gravel on it, anything should pull it with a reasonable load.
I looked at a bunch of other similar products; the "harbor freight" type guys had some $215-250 foldable trailers without a ramp or bed, shipping put them close to $400 and they dont usually have a full bed or ramp. A couple of other stores had a basic frame, no ramp, no bed, 1 7/8ths ball instead of 2" ball hitch, sub 1000lb utilities for $299.
Closest I could come to a 4x6+ with a ramp and a bed and a class 2 hitch, 2000lb load limt, highway speed capable trailer was $499 and it didnt look as solid as this one. The bed on that one was just wire mesh, so no hauling dirt or gravel type stuff.
One thing I didnt care for was that they also snuck in a $30 "assembly fee" they didnt tell me about until the DMV paperwork was all done and it was being totalled up. I should have haggled for it at that point. Better than 50/50 shot the manager waives the fee rather than tearing up the dmv paperwork and having to get a fresh title. They didnt list it in the price or on the sign, although they did note the DMV fee...a little too "hidden" for my taste.
Small trailers like this are usually insurance covered by the towing vehicle, but check your local regs. The only other charge was a one-time $36 DMV fee to register it and get plates (CA).
This is small enough to tuck into a pretty small space. I can pick it up by the hitch and stand it on its ramp, so it only takes about a 3'x5' space. Big enough to haul a big screen tv, fridge, washer/dryer, or a bunch of stuff to the dump.
I still have to haul our dead 50" tv to the dump, a bunch of screen doors, and a ton of limbs and clippings from last years shrub clearing and tree trimming.
It'll also be nice to tell the appliance and furniture people for the next 10 years to stuff their $50 delivery fees and "we'll be there between 1 and 5" BS...
I'm reaping the rewards of buying your wife a high end luxury car. She wont say 'no' to anything you wanna buy for a while...
