Thank you for making my point this is exactly why I am looking to get a model tested
And this is the response from Darko

Your truck is too big for the Darko Tech tunnel.

After your call I talked with Gary at Aerodyn and A2. The A2 tunnel can accommodate your size but the weight is an issue. Call A2 for possibilities.

Good luck with the project.
