plenty of negative responses without asking if you have plenty of leeway on weight or what size van or tug for me i made a rear bar that bolted onto the chassis rails and carried a 40 kg outboard all over the country with out any mishaps. You can always try it and if its unsafe take it off .
I fitted 2 aluminium boxes (Bunnings) and shaped flat steel to suit and bolted them to the rear bar (Jayco Freedom Tandem Axle.)
Needed space in the front hatch, too much clutter.
Only light weight items go in the boxes, also fitted on rear bar are PVC pipes holding aluminium poles, be carefull of the weight back there.
Bikes racks are a different thing again, they need holding in several directions as there can be a fair bit of weight swinging around with a back, (the pendulum effect) good luck with that part of your query.
Perhaps a call to Jayco to discuss the situation and accept there answer would be the best way to go.I know what the answer will be,but best to get the answer from the horses mouth.There are many design rules and factors involved and we the buyer and end user don't them.If you were to have an accident and an insurance claim the outcome will not be in your favour if you are out of specs.
