Yeah, but you can't ride at 137mph on the roads... Not if you expect to live &/or maintain your licence.

"...make me a tow bar for me trailer-tent"
For me personally, I couldn't go on a biking holiday with side cars / trailers / support cars / whatever carrying all the gear... it's just not the point and defeats the object... the idea is to travel light.
If I want home comforts, I stay in an hotel... if I want to camp, I camp
If I had a bike and a licence to ride it, I wouldn't tow a trailer for love nor money!
