I am assuming every DGW is on a different pppX ? If so, you can simply use
ping -I <iface> (where iface is other IP of the interface or device name).
If not, and they all go through the same interface, I guess routing by
destination like you said is the right solution...

Good tip, thank you.
Here's something I've scratched, I will be calling this via cron on a
per minute interval.
"""
#!/bin/bash
## ppp1 is the interface of Motorola V3 handheld
###
# ping
#
# -I interface address or device name
# -c count
# -i interval
#
(
ping -I ppp1 -c 3 -i 0 194.90.1.5
if [ $? != 0 ]; then {
PID_OF_WVDIAL_PELE=`cat /var/run/ppp1.pid`
kill $PID_OF_WVDIAL_PELE
ps -e -o pid |grep -E "$PID_OF_WVDIAL_PELE$"
if [ $? != 0 ]; then {
sleep 10
kill -9 $PID_OF_WVDIAL_PELE
} fi #//ps|grep $?
echo "$(date): Restarted MotoV3 ppp1 connection" >> /tmp/ppp1.log
wvdial &
} fi #//ping $?
) > /dev/null 2>&1
