You are 💯correct on the stamping of the hitch sleeve being different on each coupler during BD’s production. This has to be accounted for and calculated when drilling new holes for a proper fit. My buddy who is a machinist measured each of the 1/2” coupler holes individually and then transferred and dialed in those exact measurements onto the new 2 5/16 coupler. He totally nailed and fit was better than factory. An inside pic of how different the couplers actually are. Pic of the bottom of the 2” coupler on the left and the new 2 5/16 coupler on the right. You cannot see the difference in the sleeve fold, but it’s not the same and thus requires exact measurement of each hole prior to drilling for proper precise alignment and fitment on the tongue. My buddies tools of the trade and his knowledge were invaluable today.

New Bulldog 4B4 coupler drilled, de-burred, cleaned, primed and painted, installed and torqued down. Another project completed despite the smokin heat and humidity of the day. I could not be happier with the final product fit and finish of this mini mod. A big thanks to a close friend who owns a machine shop that does precision work. He measured twice and drilled once. For those running the S/S coupler, I applied double sided tape a few years ago on inside of the coupler to keep it from the metal to metal wearing the paint thin on the coupler. It worked great, so I reapplied it again with new tape. I opted for silver metallic to match the swooshes on XPLOR. A few mod/upgrade photos.😎 Safe Travels! My buddy Brian gotter done! Thanks Brother!!

Hey Tony, The repair kit will work on 2” or 2 5/16 couplers.

When parked at camp, I use a Proven Industries coupler lock with the optional S/S puck and Medco lock which is extremely robust. It’s just about bomb proof. **** A note to any owners upgrading to the 2 5/16 BD coupler and IF you presently use a Proven coupler lock for with a 2” ball, no need to purchase a new Proven Industries lock. Your current 2” coupler lock will work. I mocked mine up this morning on the new BD 2/16 coupler and its fits perfectly. Do not loose the keys, as I cannot imagine trying to remove either of these this locks.

Yes sir Bill, another big plus to the S/S collar. 👍🏻

Hopefully they will restructure like many companies do. Only time will tell.

We have used this coupler security and ABUS lock combo since we took delivery in June of 2020. Since it only takes less than 5 minutes to remove the BD coupler via the two bolts off the trailer tongue it’s a good deterent and better than nothing. Also when on the road it makes for an easy eye safety check during a walk around of our rig. This combo continue to serve us well 6 years in. Both have strong reviews. I will use this collar and lock on the new 2 5/16 coupler. Another plus with the S/S collar, you cannot secure the collar on the coupler locking mechanism if the coupler is not properly locked down so the clam shell cannot be moved back on the hitch ball. A nice little extra built in secondary safety feature. https://www.amazon.com/dp/B00HL2NM0K?ref=ppx_yo2ov_dt_b_fed_asin_title ABUS Stainless lock made in Germany- https://www.amazon.com/dp/B009S5Y6ZS?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1

Oliver Bulldog 2 5/16 coupler upgrade. I decided to finally pull the trigger and upgrade our Oliver from a 2” 7000# Bulldog coupler to a new Bulldog 2 5/16” 12500 coupler. I also ordered a spare coupler repair kit. These 2 5/16” BD couplers are becoming difficult to locate and purchase with Bulldog filing for bankruptcy protection in Oct of last year😳. It’s my understanding, that BD is no longer manufacturing and shipping these couplers to RV manufacturers possibly due to bankruptcy proceedings. (open source) I did attempt to purchase a 2 5/16 BG coupler from Oliver and they no longer have this upgrade in stock and available to purchase and ship. Jerry at Oliver told me they have no idea if or when they will have this coupler in stock again and are seeking alternative options. Will there will be a restructuring with BD? Anyone’s guess. I will be taking the new coupler to a friend’s machine shop to have the holes precisely drilled. If you’re on the fence about upgrading to a 2 5/16 12,500 #coupler it might be a good time to search for a vendor that has one on the shelf and ready to ship. A big thank you to @rideandfly for helping source this coupler! The Vendor I ordered from was Croft Trailer Supply in Kansas City, Mo. Ended up myself, @rideandfly and @John Dorrer purchased the (3) they had in stock. If it’s an upgrade you’re considering you may not want to wait. Safe Travels! Hull#634 XPLOR

I understand and yes, upgrades are spendy! We also use our camp chairs for drying towels which work great too! 😊

Oliver just sent this out to owners on June 30th to those who have opted receive their regular marketing emails.

We never did purchase a suction cup style bar. Our 1UP USA Super Duty bike rack it works great as a towel dryer or we just use our camp chairs. Necessity is the mother of invention. 😎 Old photo after our Truma Aventa factory install which Oliver did a stellar job on. We are so glad we got the low profile Truma when we did. One of our top retro mods.

A lot of truth..

Here- no sweeping, just open the screen door dust goes back where it came from. Helps keeping the exterior screens clean too. Neither of us wear our shoes while in the Oliver. We have found this little blower is super handy. Also works for blow drying a washed TV and inside and out. “No brooms club here” 😄 Harbor Freight - BAUER 20V Cordless, 200 MPH/120 CFM Compact Workshop Blower - Tool Only $40
