Help how heavy of a trailer can i pull

There are some walled trailers that are in the 2500 lb dry range. They're not big, but have the kitchen and bathroom without all the setup pain of a popup. I really think popups are fun - I say "pain" only because I have a bad lower back and it hurts to mess with one of those these days. We pulled a 20ft Skyline Nomad with a 2010 Toyota Sienna minivan for a year, and it was truly okay. The above advice on long distances and hills is true. If you travel on flat roads or don't tow long distances in the hills, then you'll do fine. Don't count on breaking any speed records - in fact get used to being passed on any incline, and definitely make sure your minivan has the towing package with trans cooler. Another definite is a WD hitch and sway control bar. Lastly, be careful how much you load in the trailer and van for your trip.
