Are bearing buddies a good idea?
Bearing Buddies are a great way to keep grease in a trailer hub. I recommend them as long as you are aware that it's very easy to put too much grease in a hub with these which will blow out the seal. They have no problem being used on longer road trips so the would work well for you.

Can you put too much grease in a wheel bearing?
Too much grease volume (overgreasing) in a bearing cavity will cause the rotating bearing elements to begin churning the grease, pushing it out of the way, resulting in energy loss and rising temperatures.
How much does it cost to repack trailer bearings?
So, how much does it cost to pack wheel bearings on a trailer? Surprising little, expect to pay as little as $100 and at most $400. If you want to save some money you can do it yourself, but in my opinion, it's not worth it unless you have ample experience and all the necessary tools.

How do you check the grease level on a bearing buddy?
Grease can be added to the hub through an easily accessible grease fitting located in the center of the piston. Lubricant level (and pressure) can be checked quickly by pressing on the edge of the moveable piston. If you can rock or move the piston, the hub is properly filled.

When should I stop greasing?
Measures to Follow
You can also avoid over-lubrication by practicing the following measures: Stop greasing if you note back pressure that is not normal. Check to see that the exhaust ports on a machine are free from debris, including hard crust. Slowly pump the lubricant into a machine's bearings for several seconds.
How much grease should you put in a bearing?
Typical relubrication amounts are 1/3 to 1/2 of the original fill quantity. The proper fill quantity of a grease lubricated bearing is often specified as a percentage of the bearing's free space. It is, therefore, important that the bearing's free space is accurately determined.
How much grease should be applied to a bearing?
Open angular contact thrust ball bearings for screw drives should be lubricated with a grease quantity that fills ~ 25 to 35% of the free space in the bearing. Freshly greased bearings should be operated at low speeds during the running-in period.
