1: going over to "start it up" can do more harm that good.
short term- the battery gets used to start the van---doesn't get a full recharge
long term- on a cold start, oil is not distributed through the motor- like the top end.
The piston ring fit is loose - everything is designed to expand to a tight fit...with heat.
The Fuel mixture is richer than under normal warmed up operating conditions
the result being that there will be more unburned fuel sneaking past the piston rings and corrupting your oil.
this will combine with water to form acids in the oil
also condensation will form in the cases and exhaust and not be boiled off.
so start it up when you are going to use it, cold starts are always hard on a motor- the fewer (over time) the better...you'll remember the commercials warning of cold starts and oil
( when I bring an old car out of storage- I use a fixture on a drill to turn the oil pump and pressurize the system and lubricate all teh bearings before I add fuel and spark
on a cold start, let the computer control the warm up, don't rev it or anything. keep your foot of the gas and give it a couple of minutes to warm while you check over your systems. the idle speed will drop as it warms.
You could keep foot on brake and ease the shifter from R-N-D a couple of times to move a little of the fluid through the tranny valves before you take off.
Dont; forget to check the tires!
as for a trickle charger- if no power is available, do look into a solar charger. this will help vs the slight drain of the clock and memory devices in the van.
Look into a 2nd set up for the coach battery.
If long term, remove batteries and take home- keep in a warmish place.
a fully charged battery is healthier than one which has been allowed to partially discharge.
