It depends on the age of your wdh. If it is newer you should be able to buy a set of 1200lb bars and be good to go. You will probably need to readjust the dual cam system with the new bars.
Worst case new hitch head and wd bars.
Call Reese with your hitch head model and they can help.
Just looked up your 272, and if it is the same as what is currently listed on their website you probably have a lot higher tw than 830lbs!!! That is the manufactures "brochure" dry weight, which does not even include the propane tanks or a battery on the tongue. That along adds ~160lbs for 2-30lb tanks and a battery. So now your already at ~1000lbs tw before loading the tt up with your stuff for a trip.
The best thing you can do is go visit a CAT scale and weigh your rig as suggested in my signature link.
Also, verify you are not exceeding the trucks receiver hitch rating. You could be over that as well.
