Yes, you grill has a regulator on it, the gas at the hookup is regulated.
So two regulators reduce the gas pressure so low it is not enough to light or if it did it would not produce enough flame to cook with.
I hook a hose from the tree to the Coleman, works just fine.

We have a 2014, bought a Coleman road trip grill and tried hooking into our pre piped propane tank and the grill will not work. Anyone have an answer?
I had the same issue with my Coleman road trip grill. I did a YouTube search and found a short video on how to fix it. You have to remove the thread on piece from your Coleman regulator unit and thread in a male quick connect adapter. Be sure to use Teflon tape that is approved for propane gas. I'm not good enough on the computer to give you a link to the video (sorry about that) but the hardest part is just unscrewing the end off the regulator. The video explains it all. Good luck!
your Coleman is a high pressure grill, the RV's propane hose is low pressure.
either remove the Coleman's regulator or get a low pressure grill, like Camp Chef.
you may need to adapt the hose to connect to the Coleman.
