I needed to bring home some stuff from homedepot, measurements showed it would not fit in the highlander, so I hired a van for 25 an hour, when I got out to the van it was full of packaging from the previous renter, I ended up getting the van for no cost. On another occasion I fit large boxes from IKEA in the vehicle but I had checked the packing dimensions online first, so I didn't end up trying to get stuff in that won't fit or will damage the vehicle.Know what your vehicle can carry.Having had the RAV4 which could take surprisingly bulky items, the HL takes similar items even easier and it has noticeable extra payload capacity as heavy items have less effect. The only area that it may lack on the RAV4 is rear opening height as the folded 3rd row impacts this. I will say that you should add about an inch to each dimension as vehicle interiors are curved an this will guarantee a fit.
