Width wise from memory they are all around the 2m-ish mark , so if an SR4 goes through your door, so shoud a 4.7 and a 5.4.
Whether the garage is long enough to allow you to shut the door behind it is another matter!
Have a search for garages and fit - there have been a couple of discussions on the matter.
Just remember that if your trailer is braked you may need to either take a good extra space into account or get creative wit hthe drawbar & wich like I had to do. Suffice to say my tailgate on the car will only open & clear the bow if the trailer brakes are not on.... But it fits & the door closes (just!)
