I spent most of sunday morning roaming the junk yard near the house. I figured out a few things.
1. It's harder than I thought to find a rear seat that has a center seat shoulder belt.
2. Finding a back seat that is not real deep is harder than I thought.
3. The junk yard apparently crushes 2/3rds of its inventory before Thanksgiving.
In the end I found a nice workable set up in a 2000 Dodge Durango. The only problem is no center seat shoulder belt. I was doing my usual thread reading on D-90 and saw a guy selling jump seats from a 90. He had done 4 point harnesses for the seats for his kids. Brilliant, they will bolt up nicely to the factory seat belt cross bar already in place behind the seats. Probably safer than the standard 3 point as well. So it looks like I may go back and get the Durango interior and order up some harnesses.
The Defender and I had a disagreement yesterday though, gas gauge said 1/4 tank, fuel light came on 3 miles later I was out of gas. 2 miles short of the gas station...
Oh well at least I was close to home and my wife was able to come over real quick with a couple gallons of gas.
I pulled the rear side mount troop seats out of the tub. I built a shelf/platform giving a huge flat area behind the seats. This is great for my dogs, they can now lounge in comfort. Underneath I have about a 48"x38"x14" storage area for the luggage. So now everyone is happier. I'm going to add a few tie down points and maybe a mount for a 12 volt fridge. I'll post a few pics later.
A side benefit I realized afterwards is folding down the seats gives me a bit over 6 ft of flat area for camping. Now I need to make some window screens so I can leave them open and keep the bugs out.
I need to do some searching to see what I can do about upgrading the alternator from 45 amps to something a bit more respectable in the 80ish amp range.
