My parents are taking my 3 DC camping this summer. They have an estate car with a roof box and will be towing their caravan.
They also have 2 medium sized dogs who are used to travelling on the back seat. Apparently, the plan is for the dogs to sit on the DCs' knees for the 7 hour drive 
They said the boot will be too full and there is no other option.
AIBU to think this sounds a bit dodgy?
(The children don't seem to mind and DH said he used to squash into the back seat with his 3 siblings and dog when he went on holiday as a child, so I'm prepared to be told IABU and precious about this.)
