Can a ford kuga 225 petrol hybrid tow my crusader

Only the vehicle's weight plate will give you a definitive answer, but from what I gather from the internet, Kuga plugin hybrids built before September 2020 had a maximum permissible towload of 1200kg, those built after that date 1500kg, but both those figures are less than the allowable weight of an Elddis Crusader Zephyr, so the answer is probably 'no'.
