Congrats !!
So now you just need to get it all checked out to make sure it will be road worthy. As we used to say in the Garage Business...."The care you take of it, will be the care it can take of you". Just go slow and steady to take it on a few "shake down" cruises to make sure you have all the quirks and quarks sorted out of it. Better you do that closer to home than to be far away.
Then once you figure it's going to be a sound solid Van, you could venture some longer trips.
Did you buy the Van there in Canada ? Has it been used on road trips much and lately ? If it's only been used around town, consider taking slower road trips in it to start with. 45 mph for a half hour, move up to 55 mph for the next half hour, and on up to 70 in half hour increments. This will get the vehicle acclimated to road speed driving gently. Before doing this I'd suggest an oil change with new filter (using a good quality of oil called for for the particular engine)
I drive a Ford Van each Wednesday to haul disabled Military Vets to the VA Hospital and back home. It has a Triton V-10 engine. It uses 5w 20 super premium oil/non synthetic. But it has 210,000 and runs like a top.
The motor pool mechanics take excellent care of it and each of the drivers checks the oil level each morning before starting the engine.
So learn good maintenance habits and you'll be able to enjoy your travels with more confidence.
If you wanted to spend a few dollars, you could catch some of your motor oil when you drain it. (when doing an oil change)
Then Contact this Lab for a freest test kit. (they charge about $30 USD to do an analysis) Think of it like blood work on your engine.
They will need various information about your Van and the series of engine you have. Their analysis will allow them to determine if there are issues than need to be looked at now before they become trouble. Large Commercial Fleets use these services regularly.
