We can help you with new electric drum brakes and wheel bearings for your 2007 Keystone Montana 3075RL 5th wheel. We don't have a whole kit specific to this one particular trailer but with a little bit of information we can get you all squared away.
The specs I found for this 33-foot tandem-axle trailer indicate a weight of 10,450-lbs so its GVWR is likely to be around 14,000-lbs, meaning it could have two 7K axles. You can check this in your documentation or by looking for the sticker or plate on the axle beams; usually this will tell you the actual axle weight rating which is what you need to select the right brakes.
If you do have 7K axles they will use 12 x 2-inch brakes such as the left-right kit # AKEBRK-7-SA. These are self-adjusting brakes with a 5-bolt mounting pattern that actually work with axles rated anywhere from 5200-lbs to 7000-lbs. You will need two sets. For mounting bolts you'll use two (2) of kit # BRKH12. When you wire the brakes either of the two pigtail leads can be used for ground.
To confirm your bearing parts the best route is to pull a hub and remove its bearings and seal so you can find their part numbers stamped into them. Please refer to the linked image for help with this. The most common bearings on a 7K-rated RV axle are inner # 25580 and outer # 14125A. If you refer to the linked article on bearings you'll note that two different seals are often used with these bearings, parts # GS-2250DL with a 2.250-inch inside diameter and # GS-2125DL with a 2.125-inch inside diameter.
I also included an article that will help you with the bearing replacement and one covering the topic of grease formulations. Be sure to completely clean out all old grease from your hubs.
