Read thru my thinking and feel free to offer constructive advice

============
Ladder Mount Box
============
I just got an East Coast teardrop and I am brainstorming on where to put a ladder, most likely on the side.. my unit is 14 feet long from ball hitch to the very back, so I think I could put a 12 foot { extending to 24 foot ladder } easily on the side of my unit ( passenger side of course ).. I have an entry door on both sides, so I would not mind only being able to use one side .
I am envisioning a ladder mount such that the ladder is totally enclosed in a "box" .. That way I could lock it, and fashion a way to ensure that it does not vibrate at all during transport.
I have a big "" back hatch "" meant for a kitchen area, but I likely would also use it as my climbing saddle, ropes and gear storage area

===========
Trapezoid Toolbox
===========
There is also room on my unit to mount a toolbox in the triangular area { from a top view } of the frame tubes just in front of the body of the teardrop.. The seller wisely suggested I look for a trapezoid shaped lockable aluminum toolbox .. That would be a good spot for chain saws, oil, gas, and such that I do not want smelling up the interior of my unit .
==============
hitch rack on the side
==============
I am also brainstorming about mounting what I call a "hitch rack" on the side of my teardrop at sort of waist level for a workbench sort of area.. My hitch rack is meant to plug into a standard 2 inch hitch receiver on the back of a SUV. The rack is 18 deep by 60 inches wide.. And it can be rotated 90 degrees and locked in a vertical position for transport.. I am thinking a good metal / welder person could do both the ladder mount and hitch rack mounting ..
I have decided I do not want to add vertically to my teardrop because it is perfectly 2 inches lower than my RAV4 , so I do not want to increase the drag coefficent .. I realize I am adding some drag on the side, but I believe that is better than on the top, plus it is easier to reach stuff on the side, and I do not want to introduce holes on the roof either. And of course any additions would be on the right side, that is , not on the side of the road centerline.

Solar panels
========
Have you seen or delved into solar panels used with teardrops ?? I would likely not mount it on my unit, but have something I can disassemble and put back up easily at the destinations ..
much appreciated
cheers
