Ignoring cost factors can this been done, assuming a 5 Tonne payload? I am
guessing the only real restriction is the weight of the fuel. How much more
fuel would this require than the current shuttle? I am guessing it would be
over 1,000 times more.

Stop guessing and do some research. A fully reusable TSTO ought to be
doable for far less than three orders of magnitude bigger than the shuttle!
For starters, take a look at what Space-X is planning on doing with reusable
first stages.

I was only looking for a rough guestimate, chill out, hope I didn't take up
to much of your valuable trolling time.

Don't worry about it. He doesn't have time to be nice because he's busy
trying to figure out the difference between real spaceships and pretty
pictures.

It's true that Space-X's pretty pictures are little different than the
pretty pictures NASA has put up on its web site for the stick, SDHLV, CEV,
and lunar lander. Even NASA admits that the lunar lander "design" is very
notional and likely to change.
However, the original poster asserted that he thought a fully reusable
launch vehicle would need to use 1000 times more fuel than the shuttle. I
was pointing him in a direction that is far closer to reality than his
fantasy.
