If the car is worth that much, running a Meaco DDHL Junior dehumidifier in the tent could be well worthwhileI looked at these things when they first appeared on the classic scene, around 30 years ago. They were touted as helping to prevent rust, keeping shite off, and keeping the vehicle physically protected by distancing possible contacts.
I like the idea apart from the preventing rust. It still sucks in and circulates the same moist air as is outside the bubble. To help prevent rust you need an Arizona like atmosphere, so you need to get rid of humidity. I have seen blokes plumb in de-humidifiers to these in the USA where most of the east coast is akin to walking through a swimming pool in the summer. And, in the winter the cold air so moisture laden that I have seen what look like the odd snowflake spontaneously form in otherwise clear air.
Looks like a Targa to me, what year is it? I had a 1969 911T Targa, next year when done with the house build I am looking to get a penis substitute GT3..........prices have gone stupid on them at the moment with covid, so I am hoping they will come down, or it'll be an S.
providing the twin fan airflow isn't too great. Mine is powered continuously but runs according to the need it detects to maintain the setting required. Runs throughout the winter maintaining the fully fitted interior of a 10 metre classic motor-sailer in its berth in Scottish weather. Average cost £10-15 per month for electricity. Connected to a run off, it gets left to its own devices for 2 - 3 weeks on end.
