A frame

Hello everyone!  Looking into the possibility of towing small car behind the MH. There seems to be two types - the 'standard' one with a cable to apply the car brakes or one that electronically applies the brakes. The latter being a lot more expensive! Does anyone here know about these things - and are there any problems I should know about . Many thanks in advance

The cable applied system appears to be illegal in uk now, as you lose the servo assistance.
The electronic satisfies the UK regs. But in some euro countries A frames are illegal anyway. Depends if you intend Euro travel. A trailer is legal everywhere and no more expensive then an A frame system. I can load and tie down my Smart on its trailer in 10mins,not a lot more than an A frame.

A trailer for the car(an Hyundai i10) is also a possibility but what about the added weight?

Trailer hitch load 70kg ? Or do you mean increased towing weight. Trailer for i10 should be 340kg.

I think if I were to tow the wife's Smart I'd also go for the trailer option, the car is subject to NO wear & tear, tyres especially since even though the A-frame 'steers' the car, its actually being 'dragged' round bends etc. Plus the fact the transmission will be flailing around & there is a towing range limit on many cars, then there's 4 wheels of drag vs the 2 of a small trailer, also, a trailer can be reversed, I doubt I could reverse with an A-frame!!
The weight of a small trailer would make little difference.

The advice you have been given IMO is correct over going the trailer route, as regulations have crept in in various countries over A Frames I suspect the ban will be extended further. You shouldnt have any problem wgt/power ratio with The Cotswold with its 3L engine.

Many thanks to everyone who was kind enough to reply to my question re A frame versus trailer. Certainly given food for thought! Sorry didn't thank everyone sooner but have been away for last few days.
