Thank you for the photo of the spring needing replaced.
I spoke to my contact at Bulldog about a replacement spring for your coupler, and sent him your picture of the spring. He said by looking at the spring, he believes you have the Bulldog BX1 Gooseneck Coupler, like part # BD1289000300. If your coupler is a BX1 coupler, you will want to use the Handle Repair Kit for Bulldog BX1 Gooseneck Coupler # BD500289 to replace the spring.
If you do not have the BX1 gooseneck coupler, please... view full answer...
For the 3 inch gooseneck ball size you have we only have the Bulldog BX1 Gooseneck Coupler # BD1289200300 which has the more limited height range of 22 to 24-9/16 inch. Normally a large amount of adjustability isn't needed as long as you mount the outer tube where it needs to be on the trailer. view full answer...
You are going to need to cut our your current coupler and install one like the Ram Gooseneck Coupler # GCPN-30008. This coupler will be welded in and is rated for up to 30,000lbs of trailer weight. It attaches to your standard 2-5/16" gooseneck hitch ball. The adjustable pin allows for 8" of vertical adjustment should you use different height trucks to tow the trailer. view full answer...
The Bulldog BX1 Gooseneck Coupler Inner Tube # BD1289050300 referenced is just fine for your trailer. As long as your trailer uses a round coupler tube. view full answer...

We do have some options available that are a bit longer than the Bulldog BX1 Gooseneck Coupler Inner Tube # BD1289050300.

If you are needing the 30,000-lb weight capacity rating then you can go with the Convert-A-Ball Multi-Cushioned Gooseneck... view full answer...

In order to find the correct replacement for your 2011 Heartland Elkridge you are going to need to identify your current pin box. Typically there is a sticker located on the pin box or king pin with the pin box number. If you are unable to find the sticker then you may be able to contact the manufacturer with the VIN to see what pin box it has. If all else fails, you will need to measure the bolt pattern. See the attached article for how to measure the bolt pattern and identify your pin... view full answer...
Since the Trailair Air Ride 5th Wheel Pin Box - Lippert 1116 - 21,000 lbs # LC155943 has cushioning and isn't a standard pin box it isn't compatible with an adapter so instead I recommend going with the Reese Goose Box 5th-Wheel-to-Gooseneck Air Ride Coupler Adapter # RP94716-61301 which fits the Lippert 1116 pin box mounting bolt pattern and is rated for 16K which is closer to the GVWR of your 2018 Keystone Montana High Country 330RL.
