We have 80 pound lifters in the front, 60# in the back. With the camper loaded as described, the front is tough to lift for me alone, but I can do it. With the boss' help, no problem. It also comes down well (using the fans) loaded even if the canoe is not on there. The Solar Panel is mounted driver's front corner of the Puma/Grandby.
The rear is perfect up & down with the canoe on there, a bit tough to pull down without the canoe. Fan helps.
Been using it like this for 2 years now, 100 or so camping nights. No issues with the mounts.
