Stick it on a trailer, spent thousands of miles towing things with aframes, you would struggle to get a decent a frame under a midget and clear the front valance.
And then the problem comes with trying to brake it
The older cars used to have a Bowden cable that went in thru the window and applied pressure to the brake pedal when the towing vehicle slowed,
The brake pedal lever arm on a midget goes straight onto the bottom of the master cylinder so it would be impossible to fit a remote unit unless it utilised the brake pedal assembly, then you have the problem with the front wishbones,
The rear wheel drive vehicles of old weren’t designed to be pushed backwards round a corner from the front end the Ackerman angle is all wrong so as you reverse your motorhome round a corner you are pushing on the wishbones of the mg, pushing on a wishbone makes the inner wheel tuck in tighter and tighter until the ball joints are under a terrible strain, when it can move no moreit makes the tyre scrub across the ground thus placing more pressure on steering joints, sorry to put such a downer on your purchase but enjoy yourself,
Ps forgot about modern speed bumps that will give you a fright when the steel of the aframe mashes itself into some of the steep speed bumps ?
