I'm on the fence here.
Will it actually FIT in there ? ( four people lifting 100+lbs each )
Can you tie it down ?
By the time you make something, like cardboard or wood, to slide it IN to the vehicle...THAT remains a sliding surface ..and... One slip during braking or cornering...even acceleration...and you could bust out a window. An accident or evasive maneuver will turn it into a projectile.
On the bad side...; had a mechanic's top tool box in the back of my hatchback...which slid a bit to the rear....and after a little driving, hearing it slightly tapping on the back window by now...BAM ! no more back window !
On the good side....; We used to STUFF my 92 Explorer to the gills with band gear and guys...or tow a trailer too...and have been all over the four corners and resevations and the only problem...just once ...was scary brake fade trying to stop all that wieght.
IF you can get it in there without tearing up your interioir trim...
IF you can tie it down.
Then take it with you.
Otherwise ...ship it ...trailer it...or don't take it at all.
