Hitches / Re: Replace existing ACE hitch with Bulldog?
August 02, 2021, 01:03:01 PM
Nobody has suggested why through bolting is superior to my sandwich solution? Through bolting places both the bolt and the coupler in shear. The sandwich method places the bolt in tension and the angle iron in bending, and maybe shear and requires no drilling, web cutting or compromise of the tongue extrusion.

The only safe place to drill through the tongue is at or near the neutral axis of the extrusion, where, unfortunately, I have a web. :)

The problem with through bolting is the middle web of the aluminum extrusion. there is insufficient room between the web and the bottom edge of the coupler and going above the web appears to me to potentially weaken the tongue because it is too close to the top of the extrusion. Whereas my solution, while aesthetically inelegant, does not compromise the integrity of the extrusion but accomplishes the exact same result as the through bolt. I go with fundamental engineering over aesthetics in such a vulnerable and critical area.
Unfortunately, the photo got rotated when downloaded. I thought about a bolt through and through but decided torquing it against the angle was a bad idea. Here is the concept shown in the attached sketch. Hope to fabricate more elegantly. Thanks for the input.
I suspect this ACE is also a weld-on. I've pretty well exhausted the internet and found no couplers that mount with 4 vertical bolts. I am going to apply two short pieces of angle iron, one on top and one under the tongue just forward of the jack and lock in with a bolt between on each side of the coupler as close to the coupler as I can manage. This will sandwich the very end of the tongue and the coupler. I am unable to bolt it up like the recommended system as my tongue is a two core extrusion as shown in the picture and the side pieces do not come down low enough to to allow clearance fore the nuts below that center web.

Hi, just purchased a 2013 VRV 8.5x18 Toy Hauler. It currently has a robust RAM Class IV, 2-5/16, rated gross 14,000 and tongue 2100. Have used Bulldog hitches for years and always enjoyed their ease of use. So, was considering a swap. The downside of this idea is that the Bulldog is a weld-on unit and mods are not recommended. I can live with the ACE although it hung while unhitching. (needs  lubrication). I already have an Andersen WD that I plan to mount on the trailer. The ACE is mounted with 4, 1/2" bolts in the vertical position. I can't reinforce the coupler as recommended elsewhere on this site but have worked out a way to reinforce the coupler in a different manner. There doesn't appear to be any distortion in the coupler at present but am considering the reinforcement in order to carry the additional load imposed by the Andersen. I suspect that the ACE hitch is an after market but can't find what was used on the original VRV's. Anybody have an opinion or observation along these lines? Thanks.
