I don't know about hosting a national series, but I can say at Southport we have seen a healthy intrest in truck racing this year.
So far we have had at least 1 full heat on every club day and interest seems to be growing.
For those who are up for some Truck racing this season, then Southport will be hosting two trophy meetings this summer with Trucks as a supported class.
Sunday 7th June 09 - Southport Summer GP
Sat/Sun 01/02 Aug 09 - Woodvale International Rally (same weekend as Stofold Nat.)
