3,500 max tow capacity.

There is not a lot of options in a hard sided trailer at 3,500 lbs max towing weight.

You WILL be looking at some very small trailers, most likely not more than a bed.

One of the ones that comes to mind is the Tab trailers, looks like the old "tear drop" trailers of yesteryear with today's prices :E they don't come cheap.

Another option could be a Aliner but I am not sure if they are still making them. Aliners are a cross between a popup and a hard sided trailer. Basically it has hard sides that fold up and down so you will have some setup and tear down work to do.

I personally would not use a vehicle rated that low to tow much more than a Skidoo or such since those vehicles tend to be not really designed for towing..

Here's one like we used to have. It weighs around 2700 lbs dry. It's a Skyline Nomad 186. It has a bunkhouse that you can use for great storage if you don't have kids with you. We towed it with a Toyota Sienna (3500 lb limit). No problem. Click the link below:

And here's a picture of us camping in it and the minivan we towed it with.

My neighbor has an R-Pod that he tows with a Tacoma and the 4.0 V-6. He says it tows ok but wishes it had more power sometimes. The Tacoma has a pretty beefy V-6 and a tow capacity around 6000 lbs or so. My point is the R-Pod is tiny, and the truck he pulls it with has a much higher capacity than what you are looking for and hes not completely satisfied. I dont think you will find a combo that will be much fun to travel with considering the small tow vehicle.

There are some TTs under 3,500 lbs, but not many and they are pretty small. Google light weight travel trailer and see your options.

Any TT with GVWR of 2800# or less. :Z
