Kitchen units for camper trailers..

Evening all...
We're about to have an off road trailer built (at last) to fit a tent top to, it's going to have 15" tyres 7 leaf eye to eye springs with shockies, the sides will be 500 mm.
Now to get to the question, the kitchen unit will slide out from the back with the stove mounted on the top section of the unit (similar to the Drifta units), my lord and master is concerned that the stove will be very high for her to use with comfort, being verticly challenged as she is. How high are they normally? and how do you get around the height problem (without using a milk crate). If anyone has any good picies or sites would be appreciated.
Thanks in advance,
Boo.
