I am thinking about that sofa sleeper that folds up against the wall. With it down, I can fit 2 skids. With it up, I will have full length. On the other hand, I found some pretty nice cots at LL Beans and Cabellas.I want to keep as light as I can, but have some comfort.
Here is my action plan. But not etched in stone. Insulate the van. Yamah 2400 generator, portable 9k btu AC, Mr Buddy heater / 20 # bottle, the wall mount garage organizer with the baskets (saves on a lot of weight), I do have to build a cabinet for my laptop and printer. The laptop will also be my tv. I have a big screen laptop so I bought a Hauppauge USB HDTV digital tuner with a omni directional us digital antenna. WOW, works great. Gonna add 1 gp 31 deep cycle battery and a 1500 watt inverter/charger for my coffee pot, fan and laptop. Coming out of the straight truck with that big fridge and micro wave, for me, I don't need it. Some nutter butters a little fruit till I get to where I want to eat is all I need. That's about it.
Your best bet, hire a vet! Please.
