The hitch in mine will be very similar to slee's

mderrick, do you have any side view pics of the new design mounted on your rig?

Also, did you change the thickness of your recovery points from your first design? Any plans to go thicker?

 

[mderrick]

Good questions, I will let the pictures do the talking..

 

[mderrick]

got to work a bit on the spindle design.. I ended up sourcing parts here and there and creating what I think is way over kill double shear. what do you all think?

 

[sethzilla]

Seems like more work than is necessary to me. I have a Hanna Quality bumper with dual swingouts, and I can put my full weight on the spare and see no deflection in the spindle. Maybe an interior gusset on your design to eliminate any possible flex?

 

[mderrick]

The double sheer is more for vibration and harmonics on long dirt.

 

[sethzilla]

I understand, don't think you'll notice it above all the creaks and pops of a 20 year old rig. I can't, ha ha ha.

 

[mderrick]

Sure, the first tire carrier I had built for my 40 sheared off at the top of the bumper due to fatigue over a few years..

 

[mderrick]

Harmonics being what drove the fatigue along with grain structure in the heat affected zone from the weld.. I may not run the dbl shear, it just seemed like a fun challenge design wise..

 

[sethzilla]

I like it, just seems overkill. Your design looks well thought out.

 

[mderrick]

Thanks man!

This looks good. Nice and simple. Is there a way to keep a frame mounted receiver hitch? We tow a pretty heavy camper so a rated hitch is a must.

 

[mderrick]

You would just need longer hitch bolts, all the holes are accessible.
