I realize most of the manuf probably lie(exagerate) the weights down a bit to sell them... just like people selling their fiberglass trailers... oh can be towed by any 4cyl car.
I think the listed 220lb dry tongue weight is probably pretty close...but its with one 20lb propane
cyl (empty of course) The first time I weighed the tongue of my ParkLiner
it was 290lbs, thats with 2 full propane
tanks and 2 gallons of anti freeze in the bathroom 2 hoses, 2 extention cords. I have a fridge
, air conditioner, shower with a porta potty,and furnace
Did you tow yours much? if you tend to stay in 1 park alot see if there is a summer rate and leave it there and don't worry about towing it. If you want to tow it, maybe trade in the Rav4 for something bigger. Larger 6 cyl engine or 8. Probably a reason why pickup's are so common with towing, beefier suspension. Im still contemplating next year tradeing my Rav4 in for a pickup.
