Well in fairness there is that “small” cost difference. Ours was a gift from my parents (keen cyclists themselves) and has gone to my sister now ours are self sufficient so it’ll do four kids before resale.
I’ve not tried a trail gator but every one I see including friends who’ve had them one or both of adult and child are riding off upright.
The design of the follow me means the trailer bike cannot really get vertically out of line in normal riding along. For Mrs gd, not an experienced rider, she could manage towing duties and still be comfortable and not fighting the bike even when the kids clowned around behind.
If I was planning on towing a lot/any distance I would have another.
