Experience Adding a Swing Hitch?

We really like the 3023 floorplan for our family of five. We have a very deep garage, and a 3023 should fit in two of the three bays at this house without a swing hitch (less than a foot to spare in both cases though). However, all of our previous houses had shallower garages than this, and it may be necessary in the future to have a swing hitch. Also, we've noticed that all of the used 3023's on the market currently do not have swing hitches, so my impression is that most people give up on storing a 3023 or larger in their garages and don't waste the money on an option that they can't use.

Has anyone had a swing hitch added to a Trailmanor after they've received it from the factory? I've seen several threads which refer to Dinuba RV as retrofitting their own version of a swing hitch to the trailers, but Dinuba California isn't very close to Colorado, where I live. Does anyone know of other dealers who make this modification, or has anyone had experience adding a swing hitch?

Basically, I don't think I need it here at this house, and although the various threads on cracks related to the hinge side weld imply that the problem has been addressed at the factory with newer models, it still seems like another potential point of failure that I can completely avoid here. However, who knows where I'll be living in 5 years and I don't want to shoot myself in the foot if it's impractical to add later. And on the other hand, it would give walking around room in the garage even at this house.

Any opinions would be appreciated, thanks.
