Welcome to the madness, sounds like you have been infected with a serious disease - Teardropitis. Currently there is no cure for this dreaded disease just continuing treatment to relieve the symptoms. Symptoms include visions of your next build or making changes to your current build or trailer. Walking into stores and looking at an item and figuring a way to use it in your teardrop.
Check out the design library for ideas and if search the web for Desert Dawg. Joanne built the desert dawg and chronicled her build.
A word of warning, there is another serious disease that has its evil clutches to members of this forum....DOitis. The symptoms include the sudden urge to buy anything related to Dutch oven cooking or cast iron. Watching cooking shows and thinking I can make that in my DO. Cooking in your DO when it is below freezing and thinking that nothing is wrong with cooking outside. If you have any of these symptoms and do not want this serious disease you must use all of your willpower to resist these symptoms because the only known cure is not to get the disease
I have both and I wonder why my wife looks at me funny.
p.s. there are no such diseases. If you have any questions please ask we have a wealth of knowledge and experience that we love to share with folks
