Running a wire between the batteries also means that house loads when not on shore power will depelete the chassis battery, which undoes one of the primary reasons for having two batteries. Having one with a switch (and appropriate current limiting/overcurrent protection) would be okay if you always remembered to operate the switch properly.
The battery tenders/trickle chargers you get at parts stores are different in that they are AC powered rather than DC, and I think at least some tend to discharge the battery if they are connected to the battery but not to AC power. The really nice thing about the Trik-L-Start, besides being a reliable, well-built device, is that it always just works without needing any additional effort on your part. It also has the advantage of working properly if the house battery is being charged by solar rather than by shore power, under which conditions a plug-in battery tender would not be so useful.
