Wow, Thanks for the great responses. Daws1954, Thank you for taking the time to measure all of that out. That’s just the kind of detail that I needed. Also, Thanks to Artistic Adam and Catcamper for your suggestions and ideas. Now I can move forward with planning that out. (Hey Cat, you’re right, you can never have enough hooks. How about those 3M “Command” sticky-hooks that you can re-locate if you want to without damaging the camper?).
I’ve purchased a 100 amp hr AGM battery and am planning on constructing an electrical box underneath the Trailex trailer. Set up high between the last 2 cross-member sections, it should only hang down 8″-9″ or so (well above the height of the wheel axel). In this electrical compartment I’ll locate the battery, power inverter, and battery charger. Constructed well, I think I can keep it essentially watertight and high enough that it will stay free from road hazards. Being towards the back of the trailer will provide easy access. I thought I would mount it with hinges so that the box can swing down as it opens. The whole point being that I’ll be Battery/Electrical Compartment free in the Galley area. I hit on a few great finds that I thought I would share. 1’st: A 10 piece nesting stainless steel cookware set from Magma. It is SOLID. A little pricey but well worth it. I was Very please with the quality. The removable handles are well made and pretty ingenious with how they lock on using a sort of dovetail cleat. The whole set nests down to 10.8″ X 10.8″ X 8″. If anyone’s in the market I highly recommend it. I purchased mine from West Marine but here’s the Amazon link: https://www.amazon.com/Magma-Products-A10-360L-Stainless-Cookware/dp/B002TV7QD2/ref=pd_sim_200_2?_encoding=UTF8&psc=1&refRID=KD7RQNDAXHKGZHHJ4SD9
2’nd: I found a dual fuel single burner stove from Gas One that is just what we needed. Though I haven’t fired it up yet, I’ve received it and inspected it pretty carefully. I want the flexibility of a standard mini propane canister in case I’m not close enough to a butane source. At about $49 from Amazon I though it was a pretty good deal as well. Here’s the link to it: https://www.amazon.com/gp/product/B01HQRD8EO/ref=oh_aui_detailpage_o05_s00?ie=UTF8&psc=1
3’rd: (much less cool) I found these nifty nesting wash tub sink sets on the E-trailer.com site. The drain board and dryer rack fit inside it. I ordered a 2nd tub so, of course, they nest together. I loved Artistic Adam’s version of a mini sink but I’m just not ready to go there yet. Here’s that link: https://www.etrailer.com/RV-Kitchen/Camco/CAM43518.html .
Now that I have some accurate measurements to spring-board from I’ll lay out my compartments to accommodate all of the above. Thanks again for those who took the time to reply. More suggestions always appreciated!
