You can fit at least a twin, probably a full size inside most minivans (I did have to take one out of a grand caravan recently), and a queen or king would go on the roof fine if you spec one with crossbars. Most minivans also have reasonable towing capacity, so renting a U-Haul utility or cargo trailer is less than the difference in one monthly payment between a van and a bigger truck or SUV. I’ve put thousands of miles on my 2nd gen highlander hybrid just towing either my utility trailer (5x8) or a U-Haul cargo (4x6, 5x8, and 6x12), moved twice, helped friends and family move, done dump runs etc… I’ve only rented a moving truck once, for my first move, and that was only due to limited time for a full apartment move.
I mean, it’s a hybrid vehicle that seats 7 people that is smaller in length and width than a new sienna, the same weight and the same towing capacity. It might be an inch or 2 taller than the sienna overall because I needed to add a 1.5" lift when I replaced my suspension at 195000 miles to give me the ground clearance to clear the rocks where I go camping when it’s fully loaded, but I still manage to get the 28mpg it was rated for 13 years ago. My previous 2006 highlander hybrid had almost 170K on it when I upgraded to the 2012. Hate on a Tahoe or Expedition or Wagoneer all you want because they are fucking absurd vehicles, but I bought literally the only used AWD, hybrid people mover/working vehicle I could buy, and when my 2006 hihy came out it was the only option at all 15 years before the Sienna went hybrid.
