I haven't done it on a 24v but I did replace the one on my 35U. The biggest issue he may run into is that the wires may not have much play in them. He can probably get a little more by gently pulling on the wires. The other issue is that the ends of the wires might be a little too distorted from their original mounting to easily slip into the new terminals. If the wires are long enough, it's best to snip off the ends and strip the insulation for new ends. If not, some gentle work with some pliers should help.
When inserting the wires into the new terminals, a pair of long-nosed pliers can be easier than fingers. Sometimes, pre-bending the wires into an "L" shape helps get them into the terminals.
Label all the wires ahead of time as to which terminal they go to on the transfer switch and draw a good diagram for reference. Work slowly and carefully, triple checking everything before applying power. It's important that the terminal screws are torqued down tight on the wires in order to avoid future problems.
I don't know the configuration of where and how you're mounting the transfer switch but a plywood mounting board may be necessary or easier. I found it easier to mount the switch to a board larger than the switch and then mount the board to the coach after attaching attach all the wires to the the switch. Make sure that the wires are adequately secured outside of the transfer box to avoid any movement.
Finally, mounting the switch and/or board is a lot easier with a power drill/driver than by hand.
There's a good photo of a securely mounted transfer switch here:

Good luck.
