Towing a small car

For 8 years I towed a Suzuki Swift then a Fiat 500 with a Caratow A-frame with Fiat Ducato 130bhp Autotrail.Last 2 years towed to south of France.This A-frame is heavy to lift, so you need to be relatively fit, and uses mechanical,as opposed to electronic, braking.However, it costs about £1k whereas the electronic braking versions seem to cost £2-2.5k.Others can confirm that.About 3mpg effect on economy.A trailer is an extra item to find space for on your pitch. Hitching, I assume, is down to correctly aligning the motorhome with the trailer - probably a two man job.On the other hand, I have been able to hitch my A-frame single-handed on level ground and it is a cinch with two people as you just drive the car with frame attached to the towball, your helper holding the frame.I have just got a 180bhp Swift and this appears to be even easier to tow the 500.Have had no police interest  towing in France but I believe it is illegal to use an A-frame in Spain but a trailer is OK. Just some thoughts.
