OP is the desk something like this;

If so, I think I'd be very reluctant to place something like that in an RV simply due to the physics of the way it's going to act inside the trailer. The possibility of it taking off, no matter how it is secured, and taking out a wall, window, cabinets or other items is high.
From what I've ascertained over the years is that although RV furniture is made cheaply, it is designed specifically for an RV and that environment. I know you can use S&B couches, chairs, tables etc. in selected environments but in a quick scan of my memory banks (faulty as they are) I don't recall seeing items built like that free standing in an RV - even with straps/hooks etc.
Even if you strap it down I can't begin to count the number of table legs, chair legs that have broken, come apart, fell apart of ours and others that I've had to repair. Keep that in mind.
