I use the Mityvac vacuum hand pump and it works very good. I included a
link for the hand pump as well as a canister vac pump.

I use about 10 feet of clear tubing between the and pump / tank and the bleeder valve at the wheels. I temporarily run the tube vertical up the side of the coach and back down a bit. Now I can see what is coming out of the wheel cylinder / caliper as I pump. I am looking for air and dirty fluid. When it comes out clean and air free I'm finished.
I also do what Matt suggests and remove, clean, (sometimes with a wire brush or bead blaster) and wrap the bleeder valves with teflon tape before starting. I have two new / rebuilt calipers that arrived today. I will wrap those bleeder valves prior to installing them.
When the system has been open for caliper, hose, line, or master cylinder work, I like gravity bleeding followed by vacuum bleeding. It is slow but almost all air is carried to the caliper / wheel cylinder and exhausted and all I have to do is watch and have some coffee. You can also do more than one wheel at the same time while watching that the master cylinder does not run dry.
There is nothing wrong with pressure bleeding. I have done it that way too.
