Trip to Cape York

To those of you who have done this trip may I ask for opinions.

In your opinion would the trip be easier by having a slide on camper on the back of a ute or towing an off road style camper trailer?
To me the advantage of a slide on, which I already have, is obviously not having to tow.
The downside is having extra weight on the ute. If bogged with a trailer you could always drop the trailer and winch it through after freeing the vehicle.

To those of you who have used either method would you stay with what you have or swap over given the option?
In our case no extra accommodation required for kids, but probably one vehicle only.
I have used both methods in other situations but haven't as yet done the Cape.
Looks like a bit of "automotive wading" may be involved. (;-))

Thanks in advance.
