Cheers bear, i"ll have a look at that option as well, it was the first option i thought of, but didnt know about restrictions and weight limits.
ive got to to go to Felixstowe first to get trailer, so was thinking of going down A12, round the 25 to M11, (allways go that way, a lot easier than going thru all them traffic lights on A12, especially if youre heavy)A406 down to the A12 throu Blackwall and in from that way. Was planning on leaving Felixstowe at around 4.30-5am.
Congestion charge not a problem, as i told the office on Friday where i was going and they booked it on tinternet there and then.
