Hi Frank - yes minor bits and pieces, currently need to weld a panel in the front and the footwells need replacing (have the bits all zinc primed in the garage) and my doors will need replacing, but got two new ones and they're also all primed up and when the weather warms I'll get some paint on them.
I also managed to find a suitable (drive away) tent extension for the rear that has a zipped entrance on both sides and a 1m on tunnel that connects to the rear of the van using Keder rail making a weathertight connection. The tent is a single skin thing so I designed a flysheet that will cover it and just collected that a few weeks ago from the fabric makers and it will make it very weather resistant. Having that extra space at the end makes a huge difference.
However my other plan to fabricate rigid sides for the lifting roof has been changed. I was out a few times this year when the weather was bad and the fabric sides certainly keep out the water - no leaks at all but its very very noisy when its windy, and in really strong winds I'd to pull the roof down. I'd obtained alloy sheet - stuff sign makers use thats got 0.8mm aluminium on both sides and a plastic core to make the clip-in hard sides but the connection method I'd need to use is going to be problematic so I've ditched that idea.
Instead I'm going to fasten the hard sides permanently to the lifting roof - have figured out some alloy profiles that will allow this. I can remove the fabric sides and have a properly insulated metal side. The back door presented a problem but I've solved that. Currently spare wheel carrier is bolted to chassis and rear quarter and opens with the back door (swing-away). I'll take it off the back door, move it rearwards a few inches on square channel and then clip it onto the back door (rather than bolts). The lifting roof section will have at rear a back door that is top-hinged and gas struts. When the roof is lowered I simply unclip wheel carrier and swing away, open and raise the lifting door and it pops up and I can then open the back door as normal. Advantages are I now have a 'shelter' over the back door, and when the roof is in the raised position if I want lots of ventilation e.g. in really warm weather, I can open the top-hinged door on the raised 'shell' and have a big hole to let air in!
It was inspired by a Swiss lifting roof slide-in I saw in Scotland this summer (pic below)
Mock ups so far look like this:
