Stumbled across this Web page from a Chalet LTW owner with some modifications and products translatable to teardrops. Chalet's are A-framed folding trailers and the Chalet LTW model is certifiably tiny!
This is the raves page with photos and links to items that proved to be especially useful and performed well:
A-Frame Adventures: Raves!
This includes
Rear View Camera
Align-Quik Hitching Guides
Propane Tank w/Gauge from Costco
Hanging Organizers
Collapse-able Gray Water container
BAL Lifter/Leveler
The modifications page is here.
All modifications are worth review, but the ingenious Bumper Storage might be most useful to teardroppers.
The awnings could also be of interest.
