Ideas for travelers

It's been about 8 years since I last saw this post. My answer is still the same:
Design AND produce a crowned roof that does not leak and which has mounting/attachment/gasket systems which make sense (for the air conditioners).
Hint: for starters,.... NO WOOD in roof, in sub-roof, in framing, AND in headliners. NO self-leveling goop. NO WATER intrusion, no rotting, no leaks. MORE BETTER, MORE FUN.

Hello,

I am a designer student and now I want to design a thing that could simplify and make travels more enjoyable. It could be anything. Maybe you can share experiences and tell what you are so lacking in travel?

Thanks,
Anastasia

Design a auxilary/replacement fuel tank for gas vechicles.

Design a clean burning diesel engine that doesn't need an SCR or DPF/DEF to function within EPA standards.
You'll be wealthy beyond your wildest dreams if you do.
