What is the best way to pull 4/0 4/0 2/0 AL cable 400' underground? Should I go to 2 1/2 pvc to ease the pulling? It is in a straight line.

IMO if 2" PVC is large enough, then pulling those conductors in a straight run shouldn't be a problem.

Maybe not the best way, but the easier way - let the helper(s) pull it.
In my experience, since this is a straight pull, a littel wire-ease and away you go. Walkie-talkies are key as well.

RUWired brings up a good concern. If it's something like an XLP jacket you're going to get a little more resistance than with a plastic insulation like THHN. But a little pulling compound and a good feed will do the trick. Plus it's AL so you're going to only be fighting the friction of the insulation on the conduit wall than the weight of the cable like with Cu.

You called it a 200 amp underground pull 400 feet long with 2- 4/0 & 1- 2/0 aluminum in PVC but you don't mention an equipment ground. Also have you considered voltage drop?
400 feet is a long pull if it is a 200 amp load you will have some voltage drop.
Also, is it triplex cable?

Rural residential I presume. Depending on location, POCO will probably require 3" over lengths of 150' if they do the laterals. If this is a fairly straight conduit installation, pulling the cables through the trench sticks first and then sliding the sweeps on at both ends has worked.
A second approach, (providing acceptable to POCO) would be laying in direct burial over a trench sand bed with a 3" sand cover close-in. As qcroanoke mentioned, consider the line loss and necessary conductor size needed for reducing Vdrop. rbj
