Hein, like jonsobi we got the 130 WB for the same reasons. It replaced a 26 year old 4WD Suburban (also 130 WB) that we tent camped from all those years. I have been on roads in Oregon that required backing up half way through a turn to complete the turn. We live in Seattle where narrow streets make parking difficult and backing a small boat trailer into the drive is impossible with a larger turning radius. With the dual batteries and upfitter switches it is easy to put together a 1000 watt inverter system. I chose a 20 gallon water tank, desert travels, with a 6 gallon grey water holding tank and a high quality ceramic filter system for drinking and cooking water.
I am working on a sleeping platform scheme across the back, basically two 3' x 4' sections that would fold together with 3" mattress pads inside and then stand vertical against one wall. Finding or designing a suitable hinge system is a challenge.
A last comment, I put in a cork floor, it doesn't reduce headroom much, it is quite, an insulator, fire retardant, and rugged. There a few pictures on the following link and thanks for the prompt service in getting thinsulate.
