If the Sierra is actually close to 3200 pounds unloaded as stated on the tag in the cabinets, then the van will tow it safely. What I need is a trailer than weighs no more than a true 3500 lbs unloaded. That's what all of our prior trailers weighed. My concern, is that after driving 300 miles, we will find that it weighs a lot more than the 3200 lbs claimed by the manufacturer. I thought if I could get an idea from you Toyota owners how much weight a 4-runner will tow with the 6 cyl. engine, then that would give me an idea how heavy the trailer really is.
We travel light with no water in the tanks including the hot water tank, only one propane tank full and keep the amount of junk in the TT to a minimum.
