You will find this topic has been discussed a few times - eg "I and building X and want to fly off of a grass strip that is <number less than 2000'> long".
The decision is yours and yours alone. What follows is my situation ..
Under ideal conditions, I achieve the Vans numbers. I rarely enjoy ideal conditions - a couple knots too fast or any variance to the wind or a bird or or or ...
I fly an fixed-pitch RV-8 solo off of a pretty smooth 1900' grass runway with trees at one end. It's hard to get "everything" just right. On a good day, if I am no faster than 64Kts on final (1.3x stall and not behind the power curve), I can be down and rolling to a stop by mid field when landing toward the trees. BUT, it does not take much to use 2/3rds or more. Landing over the trees I can expect to use 2/3rds. That means 1275' with no margin for error.
With the exception of a lone Cherokee, no one but me has ever landed coming over the trees and no one but me has ever taken off toward the trees. There have been a number of RV pilots who have visited. Some has CS props. There have been 9A, 7A, 6A, 7, and 8 representatives. The CS guys tend to do well; the 9A driver is a very experienced pilot with short grass strips. All are still rolling past mid-field and on the brakes.
If I had a shorter field with the trees at one end, I'd have more no-go flying days.
