Won't work, the toilet needs pressure to properly function. Yer going to need to budget for some basic components, try doing a little shopping at these places:
Tweetys.com - RV Parts & Accessories - 5th Wheel Hitches, RV Parts and Accessories
Low Priced RV Parts, RV Accessories RV Supplies
Used RVs, Motorhomes, and Consigned sales - PPL Motor Homes
Leading the WORLD in RV Parts Sales - RV PARTS OUTLET
You may be able to find better prices for the parts new that you need by shopping them online.
Another alternative is to get another dying RVing that's nearly rotted out and part out the usable bits you need and then selll the rest of it off on craigslist and use the funds netted to fund your work.
You can usually find free or close to free rigs to part out if you look.
Another reason you don't want a suspended "gravity tank" approach is the water higher up will mess with your handling. Just go and get yourself a used 25-30 gallon fresh tank off a parted out RV or do above as suggested.
There's no real point in nickle and dime-ing yourself into a less enjoyable rig, do a search in your phone book, there may be an RV salvage shop in your area you can buy used parts at at a discounted price, I know of one in my area that I've gone back to get old 70s components more than once.
