When I originally had my rear hitch mounted for my bike rack, I simply had the welder mount 4 (6 1/2 inch) receiver tubes on each corner. Here's the front receiver tube mounted to my Little Guy rack:
And the rear receiver tube mounted to the frame:
And without that - I wouldn't have this: Teardrop Side Awning Solution!
Or here's something else. 95% of teardrops have rear kitchens and this area is obviously the most used and functional part of teardrop camping. Many teardroppers may be apprehensive about getting a rear hitch to carry bike racks, cargo carriers, etc. because it would be right smack in the middle of the way. But after arriving at your campsite, this...
... quickly turns into this ...
Your bike rack, extra cargo rack, side table, solar panel, whatever, is completely out of the way but still mounted, secured, and functional at your campsite. You could even carry a larger cooler on a cargo rack, or even better, a big hitch-mount grill or some other cooking apparatus, and it would be out of the way but still right there close to your kitchen. Or you could have multiple accessories mounted... the possibilities are endless. Many times I will have my side awning on one side, a 9 foot market umbrella (Automobrella) on the opposite front corner over the platform and door, and finally my bike rack on the other rear corner receiver! And lastly, another good thing is that your rack and bikes are locked and secured to the tear providing good theft deterrent.
The 4 corner receiver tubes don't have to be as heavy duty as your primary rear carrier hitch either because you're obviously not traveling with items attached to the side of your tear. But we estimate my corner sleeves to hold at least 150 pounds each. Put it this way, well over what's needed for the type of stationary purpose we are talking about here. I don't think anything of having my rack with 3 bikes on it. In fact, I have come back to my campsite to see friends actually sitting on the support bars for my side awning! I don't recommend that and let them know it, but point being, those welds are good.
So how 'bout it TD Manufacturers? What do you think? Just send me 25¢ for each receiver you mount or donate it to the wildlife fund to save the whales or something.

This is a quote from the thread about my side awning:

The pics you just put up of the receiver sleeve mounts on each corner would be a brilliant extra addition that, if offered as a mfr option, would really enable some cool options for owners.
And when I get the SunSpot into the shop...what perfect addition to my frame.
Well you can bet that Little Guy and other manufactures look in on this forum and take notes, so I wouldn't be surprised to see the side mounts put into production. It just too easy to do it and it makes too much sense. I used to keep in touch with the guys at Little Guy when I first got my tear but it fell off with the challenges I faced in the past year. It was really good when the company made a concerted effort to become a part of this forum though - so they'll get word of it.
