Wow, that's very similar to what I bought 2/3 years ago. 2001 focus estate with 135k on the clock, now kicking 170k and about to die.
The boot is phenomenally well made, small wheel arches, completely flat, no raised bit out of the boot, boot raises up as a rain canopy...perfect sleeper. Very comfortable, although I'm 5'10 and can just about lie flat without any room to spare. If the mondeo is the same quality boot layout but bigger I'd expect it would suit the OP perfectly.
