That amount of weight placed that far behind the axle on an add on platform would create problems on the steering axle right off and create a very unsafe operating condition.....to put the platform on the rear would require some extensive modifications including to the coaches frame just to attach and support it.....all of this would become costly and in most states 4' is the maximum overhang on a vehicle

the only time it is tough to tow a toad is when you get out and look at how long it is.....not to mention it doesnt cut your fuel mileage enough to worry about

Why not tow 4-down, as Bear said?

But if you insist on a platform for a smart you could use an Idaho Tote. There is a version that can handle a smart.  In some states this is considered towing doubles if used behind a trailer, though. And if used behind a motorhome you have the same issues of what to do with it when getting into camp as with a Dolly. 4-down is much better. And easier.

 That would be the the simplest and most common way to do it.  The Idaho Tote is interesting. 

The whole idea came to me when I was looking at the PowerHouse conversions website.  They had one model with an extendable 5th wheel and I thought, if it could handle the weight of a 5er, why not a smart car for example.  Yeah it would be complicated and expensive.... The pro would be less wear and tear on the toad.  As I think further, it now seems more pie in the sky thinking and impractical.

You may want to check this out!! Go to ElioMotors.com It looks like that Can Am reversed tricyle but has a cabin; gets 84 MPG and costs $6800.00. I can't remember if it is just a rider or has room for a passenger. Also don't know if the power is driven from the front or rear wheel.

I would interested on just how much weight that smart car is adding to the MH. Even it had a tag I would imagine the rear would be overweight. When I checked into adding a hydrolift to the back of my MH with my Harley ultra classic it was going to add 2200 lbs. that eats up a sizable portion of my CCC. The Harley only weighed 870 and the lift was roughly 400lbs.

The problem is the distance from the center point of the rear axle to the center point of the lift. In my case that was 13'. Then you have the problem of cooling if the a coach has a rear radiator. Most coach mfg. like you to have an obstructed flow to the rear of the coach.

Towing 4 down is the easiest way to go. You have less stuff to deal with when you camp. Box trailers may not fit into your camp site. Then there's the additional maintenance.

I like the concept of the smart car on the back of the MH but it creates concerns for me.

Now that I think about it a 36' to 38' tag might be possible. The rear axle and tag would be closer to the rear of the coach, just a thought. Might be worth investigating.
