Do you know exactly what you'll be flying in Dubai? I ask since the first low wing aircraft I flew was a Cherokee 140 (after C152) and the wing was no problem but, by Holy Harry the window winder handle in the roof for trimming and the lack of any toe-brakes certainly were.
As has already been said the fuel pump and fuel management system are the only real differences. At least you won't have to worry about the weather
