Paul is it going in a van you own or are hiring?
If its yours maybe take a look at these
www.motocinch.co.uk im getting a set for my crosser and 2 sets for taking bikes to trackdays, theres a few vids on youtube of people using them too
If youre just hiring, what youre suggesting should be fine. Front wheel jammed up against the body of the van, the ratchet strap taut so bike cant rock left or right. I always think more ratchet straps wont do any harm
