Whole Wheat THICK Pizza Crust

Really this is my mom's french bread recipe but I use it for Pizza crust and if you like thick yummy pizza crust, you'll like this.  This recipe makes a LARGE and FILLING pizza... it fits in big 18 x11 (or so)jelly roll pan with 1 inch sides.

So here is the RECIPE:
2 1/2 cups warm water
2 tbsp sugar
2 tbsp yeast (or two of those little packets)
Instructions: in large bowl let yeast, water and sugar dissolve for 10 minutes.
Then add:
1 tbsp salt
2 tbsp oil
3 cups flour (you can use white flour but I always use whole wheat)
Instructions: stir together well in your mixing bowl, I have my kneading hook on my kitchen aid that I use for this part.
Then add:
3 more cups flour and stir and knead together until all is mixed.
Instructions: Then let rise for 20 min in a warm dry place, punch the dough down and stretch dough out to spread across your GREASED (I just use spray stuff) and then I bake my crust @ 350 degrees for about 10 minutes to give it a head start, then take it out... add all your ingredients and bake for another 15 minutes.  And your done!  It will be really lumpy... and thick but it is sooo good and really one piece fills you up. (for French bread I let it rise twice for 20-30 minutes and then just make a big ball and set it on a cookie sheet and bake it for 45 min or so.)
Topping suggestions: 
-Your favorite kind of Spaghetti Sauce (I use this because then I get all the flavors that are already in the sauce)
-Cheese (duh)
-Grilled Chicken pieces
-Spinach
-red pepper slices
-tomato slices
-and then season with garlic salt and oregano... yum.
