I did manage to WFH at the van a few times, including WFH in the passenger seat of the car whilst driving to see the Red Arrows at RAF Valley (and finished the meeting with the laptop on the car boot from a field just before the aircraft took off). Can't do that from an office. At least I may get some more flexibility out of Covid and can WFH a bit more. Really would love 2 days a week at home. Fridays will be easy as we never have any academics in on a Friday, so no meetings.
That was the biggest downside to covid for me, stuck at home furloughed for 3 months in glorious weather but unable to spend it at the van. Absolutely balmy that i could drive as far as i wanted to spend time in a crowd on a beach but couldn't sit in my own property with all private amenities.
We got £300 back onto our 'account' and 2 months extension for free, to be taken 2 months this year, or split 1 month this and next - that bit never happened as we shut the van at the end of September knowing we'd not be allowed back in the country.
Our's isn't a cheap site, but glad they don't chuck vans 20 years or older off - ours still looks new.
Our decking is mainly timber, but plastic deck. The balustrades are plastic, but it's all timber under the deck, and the legs are timber covered in a plastic 'tube'. We had to replace a small section of the deck under where water collected and rotted one of the decking joists.
