Carrying bikes and towing a Dandy

Hi
we have a cycle carrier that fits on the back door/window of the car.
are we putting too much stress on the car if we carry bikes and tow Dandy?

Technically you can look in your car hand book or on the plate under the bonnet and check the various weight limits. Alternatively, what does it look like. Is it back down front up or level. What is prompting you to ask. Are you putting lots of weight in the car, 6 kids 3 big dogs, 2 adults.

A lot depends on the weight of the bikes and what car you have and what dandy you are towing. If it's a range rover probably OK, if it's a fiat 500 probably not.

So, we need some details please.

As Navver has said we would need more details before anyone could give you an answer.
