Hi Chickade. Welcome to the forum! I'll attempt to answer a few of your questions, although there are many folks on this forum who have vastly greater experience than I. Therefore if I were you and someone posts something different than what I say, I'd go with their response. I'm also pretty new hear as well. But since no one else has posted I don't want you to feel ignored. It's easy to feel overwhelmed. Just take it one step at a time. It looks like you have yourself a very nice van.
How do I learn to use my mirrors to manage the visibility issues of a van?
I was about 19 or 20 when I first started driving a 15 passenger van for work and also a U-haul type box truck (I think that's the correct term.) I will admit I was nervous at first but really that went away with experience. The more you drive and use your mirrors, the more 2nd nature it will become. If you like to read about things to learn them you might check out your owner's manual or maybe a beginning driver's book from the library.
How do I learn to drive a large rear wheel drive vehicle in the snow?
I learned how to drive those larger vehicles in snow in the midwest. I've been to Phili once and I saw how hilly it was, nothing like where I was in the midwest. Do you know anyone who could give you some pointers? My dad taught me how to drive in snow when I was a little kid (actually drive in any weather.) He took me to an empty parking lot and had me do turns again and again until I understood how to handle a vehicle that was skidding, etc.
Do I need snow tires, and if so, do I need two or four, what type and size?
I never used snow tires in the midwest but ymmv. Maybe call a tire shop and ask the advantages of snow tires. Of course they want to sell you some but ask what the downside is to not having them. Then ask some friends if they put snow tires on their cars. Network. The size of tire you can get on your tires right now. Most tire stores have a way to look it up online by putting in your vehicle make and model info. Your service manual would have the info also, I believe. I know the tire pressure is listed on your inside door panel, probably your tire size too but to be honest I haven't looked at that sticker in a while so I forget what's on it besides the VIN.
How do I change the turn signal bulb in the rear tail light?
CHeck the service manual for your van or google it.
How do I get help with problems like light bulbs or do I have to go to a mechanic?
You could go to a mechanic for that but I hate to pay a shop rate just to change a light bulb. On the other hand, I doubt a shop would charge you if it was just putting in a lightbulb and it was simple and they were slow.
I've been asking about how to get more mechanical experience myself so you might search this forum, look under mechanical issues.
Also search a forum for your type of van-just google " " van forums.
Read your owners and service manuals.
Look for classes at your local adult ed or community college or even mechanic's garages. Somewhere you'll find someone giving a class on how to change your oil, do tune-ups, etc. I'm taking a class in my city this month on changing oil in a vehicle. Again, Google is your friend and YouTube also.
I've started watching Eric the Car Guy lately on YT.
Maybe check out car clubs in your area next Spring.
Start with small things and as your confidence grows you'll take on larger tasks.
Do conversion vans have different interiors than regular vans?
In a word, yes. If your conversion has a bench that folds to a bed, then it's different then a cargo van (empty space behind driver and passenger) and a passenger van (has seating but none turns into a bed.)
If the interior is different how do I find documentation on how it is different?
Again, look up on google and look at pictures. Look at pictures on forums, before and after. Why do you want to know how they differ? I'm not understanding your reason for asking the question. If you're planning on personalizing your conversion to work for you, you'll end up with a van that is probably a little different then anyone out there. Before and after pics on forums are a great way of getting the ideas flowing. YouTube also has videos on people who have customized their vans. Check it out.
Perhaps you can direct me to the best part of the forum to get answers to these questions.
You might want to start looking in the van section if you're looking for answers to how to start a conversion. There's also great write-ups on the website. I don't know if your other questions would have answers to be found within the forum itself, but maybe. Start using google and youtube and you'll be surprised by what you can learn. Also check out your local library. Librarian's are an underutilized resource. They can help you find not only books in the library but other things in your community in your interest area.
I hope this gets you started. Someone else might chime in with more detailed answers. Good Luck and keep us posted.
