OP has 5 bikes to carry! This was my problem w/minimal options available. The kids have quickly outgrown the smaller bikes that are a little dodgy on it. 6 bikes on any vehicle with 2" receiver and it'll hold up to much abuse. I know! The 1/2" heater hose for handlebar padding is a bit worn when I was dragging my bike along I-70 in MO. Easy to replace that and the bungies are still going strong for me, even after that mishap. I have spares in case needed.
Go Lolo...

you can also grab **** out of the back from the glass without any fuss if you aren't a fat ***.
It held up great last summer from PA to MT and almost back to PA on the back of my camper...until Missouri! The Lolo was definitely not the weak spot and I got a sweet new rim and some other components for my bike (the longest one ). Lots of sparks! Sadly, won't be putting it on the camper again cause the frame is welded/repaired/**** now, but, Lolo is definitely the best option for my family... I used it on a really rutted and rough road on the expy out in MT and the bikes were rock solid the whole time. Low fuss to take them on and off, too. Highly recommended
