I made my own. Made the frame and used a tire holding Swagmen 2 bike rack I can take off and put in the truck receiver if we want to take the bike for a day ride somewhere beyond the CG. Don't know if you have access to doing this, maybe a welding buddy?

Bike rack for front of TTHeads up, my rack and 2 adults bikes added 110# to the loaded tongue weight. My camper A frame, truck and WD hitch can handle this. The bikes do ride very well on the front. 4 bikes, if you can actually fit 4, will add more. Carrying bikes with an SUV is always a problem. We had a 2500 Suburban and had the same issue. The F350 which was needed for our current camper solved the problem by allowing added TW to make the A frame rack work.
A place in Canada called Top Rails or Top Pop Rails used to make this too. A very good system. I do not know if Arivka bought them out or not. I cannot seem to find that brand any more.
Stromburg makes this
