we are just starting out camping and have bought a tent a royal tampa 4 2011, we are having a hard job trying to find a groundsheet/footprint for it. we done internet searches and spoke to countless camping shops to no avail..... we were recommended by royal and camping shops to come on here and ask the masses if you know of anyone that has one on a shelf that does not know what to do with it.
The tent came with a sewn in groundsheet ("SIG"), so unless yours is somehow absent, I'm guessing your talking about the "footprint" which goes down first and helps protect the SIG.
There's one in stock here or the alternative is to make your own with something from B&Q. This shows the shape. You'd make it an inch or two smaller all round to avoid rain being channelled underneath.
Good luck and happy camping.
