The caravan was a 1991 Castleton which probably has a bit more curve in the front, to ease things, than the Bailey. But I feel the 110s spare wheel stuck out more relative to the centre of the tow ball than the Discos.Hiya
Which van do you have? we have a 2002 senator wyoming - any idea if it would fit?

In your position I would do a simple check myself to better understand how much room I had. Cut a piece of small section wood [1.5"x 3/4" ]the length of your bike and duck tape it horizontally onto the spare wheel. Then if when playing things make contact no damage will result. Caravan hitched up put it on full lock travelling forward. Stop when the radius is developed and get out and see what clearances you have. From this you should be able to make a reasonable judgement of how much would be left when you add in the stand off of the bikes.
I feel with 3 bikes your pushing it, but two could be on.
I turned the handle bars inline with the wheel.
