Bikes, maybe not. Try gen set.
My bride was unnerved by the wiggle the front mounted bikes displayed while navigating our uneven Alaska roads. The play seems to be in the mechanism that allows the bike rack to pivot forward - which was useful to those using the rack behind a vehicle hatch-back, I suppose. Before I give up completely, I'll snag some UHMW from the local shop scrap heap and see if I can snug-up that area. The receiver is snug with a bolt-thru pin.
We put one ebike on the Fiamma for the trip back, and that worked great. So am considering mounting the Champion 3400 to the front of the TV, and carrying one bike on the Fiamma and one in the bed of the TV. Too bad that two ebikes exceed the Fiamma capacity by about 25#s, even with the batteries removed. But I am of the "better slightly under the load rating than slightly over" school. RVgeneratorboxes.com makes a great platform; I will fabricate a cover.
For what it's worth: the Adaptive Cruise Control worked fine with the bikes out front.
