Does anyone have any links to any bike racks that connect to the 5th wheel pinbox in front? Preferably 3+bikes(2 adult and 1-2youth). I've tried searching but coming up with limited results.

Trying to get away from the rear mount if at all possible.

Plug and Play: Fifth-Wheels ? Quality Bike Racks for your RV | ARVIKA

 

I made my own and if you do a google search you will find several ways to mount a standard rack to the pin box. I have a long bed and I made the receiver below. The actual rack is a folding 3 bike rack from www.discountramps.com . I carried three bikes for 7 years like this without a problem. If you have a short bed, a similar receiver and a hanging style rack will work well.

 

I like what Monty has done here, but if you have a shortbed truck(like me), it just wont work. I had a local welding shop fab up a hitch that welded to the frame on the back end of the fifth wheel. You do get more bounce back there, so my recommendation would be to get a RV rated bike rack that is platform style, vs one where the bikes hang. Much less leverage for breaking things when running down the road.

 

My 5th wheel bicycle solution was a front mounted receiver on the truck. Works great and comes in handy for other things.

 

I made my own on both my stock 1621 pinbox and the now Airride pinbox. I used some 2" reciever stock and rectangular tubing with a Thule 4 bike folding/tilting bike rack. If I kneel the 5er down and tilt the rack I can get the bikes on/off from the ground or I stand in the back of the truck to get them down.
What pinbox do you have? Do you have a long bed? The only concern is with a short bed having the bikes contacting the cab.

 

I built one using angle iron and a Harbor Freight receiver. When your pin box is level find your angle so the welded receiver is level once installed. I bolted mine on so I could later change out parts on the pin box. I like the 1-UP USA rack because when they are mounted the rack sits up at a slight angle giving more room for my fuel tank and toolbox in the truck bed. I three position rack would be sticking quite a ways out. I started out setting the bikes up with the bars as we ride them but now turn them 90 degrees. I was getting a handlebar hitting the nose of the 5thh wheel. The only damage was the handlebar handgrip wore out. Could have been worse.
I would not expect this to work well without a full size truck box.
I started using the spray on bed liner paint and it works better long term than the normal black rattle can.
I made a stinger with a flag pole holder for when the bikes are not with us.

Locating the best fit spot to mount and checking level. I measured the bike rack for the distance the handlebars would be to the nose and left a few inches clearance when finding a place to mount the receiver to the angle iron. Using a string line from the cap down gives you a good idea of where the bikes will sit.

I rolled some rod for a hold down and lock point.

Checking angle before the final weld. (Level the work table first.)
