I have just this morning ordered a Synergy STF box from Rover ron has any body already got one of these, if so what are there expieriences with it? I must admit I can't wait to get it to see what performance difference it makes whilst towing. One doubt I'm am having is I haven't ordered the dash mount switch and think I should have! Oh well but I'd love to hare from any one so I'll half know what to expect!
