Did not mean to start a controversy. But here is my view on a few points that were raised:
1) A trailer behind a car makes driving unpleasant.
For the most part I agree. The issue in the US is that most trailers pulled behind cars are of the landscape trailer type. No brakes and a simple leaf spring suspension.
If you look at most european trailers like mine (BMW Multitrailer) they have independent suspension, coil springs, gas shocks, radial tires, mag wheels, and at least surge brakes. (hydraulically coupled brakes on the heavier trailers). It follows the car and you can not tell it is there. Braking, curves, crosswind, whatever, you truly forget about it. Until you back up...
2) Towing a BMW behind a Mercedes.
Guilty as charged! I started out with a BMW X5 tow vehicle but since I now work at a MB Dealer I got a better deal on an MB. We have been able to take trips towing the bike behind the car or our Motor Home that we could not have done otherwise. My preference is to ride. But parking the Motor Home at a nice place and taking day trips makes it much more attractive to the spouse. For CCR we will tow to Denver with the Mercedes and ride from there. That gives us more riding time on the good roads. West Texas and Oklahoma on the Interstate are not my idea of a riding adventure.
4) Trailer behind a bike?
set up correctly I believe that it is a lot safer than a bike that is totally overloaded. I have seen a few trailer rigs that scared me, but the folks that show up at CCR's with trailers all appear to have it well thought out and I have not heard of any trailer caused accidents among our members. Once I retire and have more time to travel I plan on getting a well engineered trailer.
5) There were some references to age
They must be aimed at me...Thank you guys! I am catching up to some of you
