A method of concurrently connecting the pipework 21 of a fuel loading or unloading facility 20 to a leading tanker trailer 12a,b and a rear tanker trailer 13a,b of a longer than standard vehicle dual fuel tanker combination 10a,b, and a drawbar therefor. 5 Such a combination may be up to 26m in length. The combination 10a,b has a prime mover 11a,b to which the leading trailer 12a,b is articulated. The rear tanker trailer 13a,b is mounted on a dolly 14a,b connected to the leading trailer 12a,b by a dolly drawbar 50,150. The preferred method includes the steps of: positioning the rear trailer 13a correctly to connect to the loading or unloading pipework 21; fixing the 0 rear trailer 13a in position independently of the leading trailer 12a and prime mover 11a; and adjusting the length of the dolly drawbar 50 to vary the distance between the leading tanker trailer 12a and the rear tanker trailer13a. The leading tanker trailer 12a and the rear tanker trailer 13a can therefore be concurrently connected to the loading or unloading pipework 21. Fig. 3a Njj
