Nice write up.
I loved watching the YouTubes you got setup. Shows the speed of the Strida EVO with road traffic AND whilst hauling your Travoy Trialer — AWESOME!
Just a bit on the comment you wrote " I may also experiment with these removable pedals. They are lighter than the folding pedals, quick and easy to remove but I may miss the ability to fold the pedals."
I used removable pedals as I don’t like the folding ones. Also I like how they offer more security in that whilst one of the Strida features is I don’t need to lock it up – I do roll it into cafes, my office, etc… but I don’t always keep a sharp eye. In some cases I walk off to the “gents room” and walk back out and it’s unsecured! I detach the pedals and pop them into my bag… no one can get too far with a bike with no pedals. 
I am using these MKS detachable pedals and absolutly love and recommend them. Link: https://www.mkspedal.com/?q=en/news/node/253
The only downsize if - there has been times I rolled the bike out, don the helmet, and all - and realized I left the (detachable pedals) inside the apartment.
PS: That youtube and Burley Travoy is awesome and makes me want to go on a long trek and camping! I really could haul all my stuff…
