hi, just bought a Fucare libra for me and my wife. i was impressed with reviews and the specs. but i didnt pay attention to the weight. they are heavy. anyone else got these? i did see some negative comments on here about them. i bought a bike rack for them rated 200lbs cause they so heavy. i got it and spent couple hrs to assemble and figure out how to put bikes on it and then find out the 200 lbs was derated down to 120 on a motorhome from a car or a truck or minivan. so, i sent it back. and, looking for a good rack for 2 Fucare Libras at 81 1/2 lbs each for a motorhome. anyone using one and have comments? please tell me
