If not, how do l securely strap them on top of the car? What do l use to tie them down to the car?

Use bungee cords and rope to attach it to the top and drive slowly, also depends on the distance your traveling.

l dunno. how wide is the door opening in the back, and how wide is the bed? Most full beds are something like 54'' x 75'' So the cargo area should have an opening of at least 55'' and be at least 75'' deep or you will have to tie the doors closed. The opening must be at least 55 because you can not fold the box.

What is it with people who go to rather than going to the right place for the answer. A tape measure and the car.

Well, l do not own an escalade or know anyone who does, so l can not measure the opening for you. If the seats come out, then that will be a good start.

If u decide to tie it to the roof, make certain that u tie it very well in the front & be sure to but the box spring on top. If u put the mattress on top, it is likely to bend up if u get going very fast & will possibly damage the mattress. To tie it on, if nobody will be in back, start the tieing there by opening the window on each sideand running the rope or whaterver into the cab, tighten it like crazy & tie it, u may want to put a soft cloth between the paint of the car & the rope so u dont scratch ur car. Once u have that done, u can jump in (make sure u r in the car before u tie the ropes in the front or else u will have to climb throught the window), & repeat what u did for the back.

Good luck

you could make it work if you dont have to go that far with it you could always leave the back open and bungie cord it so it wnt slid out of the back if ou have stoe and go seating the yu could get it further in but still wont get it to lay compleatly flat hope this helps you

If it is the Escalade truck you have, then it is made like the Chevy Avalanche, where you can pop out the back window, flip the rear seats down, and fold the back down to convert the cargo area into a full size truck.

If it is the Excalade SUV, then my suggestions is to strap them on the roof.

.and why are you asking this question in ''Dodge''? GM SUCKS!!!
