I have two concerns with the 1Up on the trailer, both caused by the excessive bounce at the rear of the trailer: (1) possible contact between handlebars and the rear of the trailer; and (2) front wheels popping out of the wheel arms on the rack.
I experienced both of those issues on our initial trip. Admittedly I only had handlebar contact with the rear of the trailer (fortunately with no real damage) when carrying three bikes (two 29er mountain bikes weighing 25-30 lbs each, plus one 15 lb kids bike) before I knew that 1Up recommends two bikes max on a trailer. So with one or two bikes I would have less of concern with this issue, particularly if one tightly wedges the pedal against the spare tire. Also, as noted above my bike is an XL with large tires and long wheelbase, which I think also has an impact.
However, I did have a front wheel come loose from the support arm and slip off of the wheel tray when only carrying two bikes (my 29er and the kids bike). Based on this experience, I would still use the 1Up for one or two bikes on our Escape, but only if they were lighter and smaller and/or with narrower handlebars (e.g., my kids' bikes, 26"/27.5" wheel mountain bikes, road bikes, etc.). I would be hesitant to haul a 29er again or fat bike unless I was only carrying one bike, and in that case I would also take measures that Old Skool describes above.
I know others have had much more positive experiences without any of these issues, so I would consider the type and size of the bikes your carrying, the types of roads you travel, etc.
