My 21'
Escape has a factory 2" reciever in back, labeled "MAX 150 LBS". my RV rated Swagman Escapee2 bike rack weighs about 30 lbs, my bike weighs 27-30 lbs (depending if its got the rack trunk bag on, and water bottle), my wife's homebrew ebike weighs about 50 lbs without its
battery pack, and when I load this, the tongue
weight of the fully loaded trailer is barely 400 lbs, which IMHO is too
light for a 4500 lb trailer. that said, we towed that combination 3000 miles last spring, California -> Nevada -> Utah -> AZ, and home. But I'm towing with an F250 longbed diesel, thats an incredibly solid and heavy ride, so not much bothers it.
