I Need Advice on a 5th Wheel to Gooseneck Adaptation

[Xfaxman]

I like the idea of the companion hitch. It's too bad it's so expensive compared to other options. It's also too bad Diamondpilot is in Indiana. I'm in Idaho, and that would be a long drive to pick up a hitch. My trailer is only 17 foot, but it's likely that we'll upgrade sometime in the future.

Another question I'm hoping to discuss here is what, if anything, do I need to do now that I have a short bed truck? There's a guy locally selling a Popup brand hitch adapter for the trailer at what I consider a good price, but it's a straight down type of hitch. There's no offset. What are the factors that will help me decide if I need the offset?

How wide is the front of your horse trailer? The ones with a slight taper at the front will usually work in a 6.5' short bed.

In a big open area like a field or a parking lot, pull forward while turning right. Watch the corner of the horse trailer as it gets close to the back window of the truck. If you can do a 360 degree turn, you should be good to go.

If the fifth wheel is wider, it will need an offset adapter. And be very careful turning sharp while backing up, with either trailer.

The horse trailer is a featherlite with a narrow nose. I'm not worried about the horse trailer.

I'll have to go and check the camper. That's the one that I have to modify.

I measured the camper. It is 86" wide. The center if my hitch ball is 35" back from the front of the truck bed, and the bed is 63" wide from inside to inside of the bed rails.

I got a hitch adapter and installed it. It is the popup RV3. I have plenty of turn radius in the truck, but it's not going to work because the camper nose is too high. The camper frame comes uncomfortably close to the bed rails of the truck. The adapter I have is adjustable, and I have plenty of room to increase the height of the hitch. The problem is that with the camper jacks maxed out even with 8" blocks under them I have less than an inch of clearance with the ball.

All this comes of buying a truck with a bed height half a foot higher than my last truck.

I could flip the axles to get more clearance and use higher blocks under the jacks, but my family has almost outgrown this camper anyway. It worked great when my kids were little.

If only money grew on trees.

That is by far the smallest 5th wheel I have ever seen.

I know. It's awesome! It was perfect for us for a long time. It fit my young family perfectly, and it was the perfect match for my half ton truck. Unfortunately both the family and the truck have outgrown the trailer. I still need to sell the old truck, and we're considering selling the camper and truck as a package deal.

Looks like the jacks are held on with U bolts, Why not loosen them and slide the jacks down 4-5" so the fixed tube of the jack is even with the bottom of the frame ibeam (ie: so that in the attached picture, the red and yellow lines line up)?

Flip the 5th wheel axles. The truck is too tall, and you can't adjust your pinbox to make up that much(on the compact 5th wheel, do you have adjustable pinbox?).

My stock Ram 2500 is tall enough, that my '98 Wilderness 5th wheel needs the flipped axles. Otherwise the back of the bed would be hitting the underside of the RV. My 5th wheel effectively has about 4" of "lift kit". It matches my truck great, but I carry 4" blocks to put under the jacks. And, the bottom step at the door is at an odd height. And, there is a large space in the wheelwells.

I had to do the same thing when I bought a 2013. All 3 axles on my Toy Hauler. Also had to modify front and rear steps splitting the difference between first and last step into RV. Works OK once you get used to it.

The jacks are tack welded in addition to the U-bolts. Taller blocks under the jacks would also meet the need.

I do have adjustment in the pin box. I also have plenty of adjustment in the adapter, too.

Thanks all for the suggestions. There are a lot of people around here driving RV's with flipped axles. If this camper were still the perfect fit for my family, I would flip the axles and not look back. As it is we are growing out of it. My kids are no longer toddlers and infants. We've been considering an upgrade, and this is a good opportunity. Not only would the family be more comfortable in a bigger camper, but I have a big enough truck now to be comfortable pulling a bigger camper.
