Hi, I'm looking to buy a tent trailer to be towed by my Toyota Sienna Minivan with a V-6. This is my first tent trailer. My Sienna has a GVWR of 5,250 lbs., and Gross Trailer Weight Rating of 3,500 lbs. Based on that, what should the max dry weight of the trailer be without pushing the limits? Also, I'd like to park in my garage, so looking for something that has a closed length of less than 17ft w/ a shower (wife's requirement). Any recommendations on make and model? Much appreciated.
