This is your conversion tier list. Ram Pro Master, F tier, Trash, Diesel Sprinter Van, S tier, Super, Econoline RV, F tier, Trash, Gas Power Transit, A tier, Nissan NV, D plus, Diesel Transit, B plus, Scooly, D minus, Gas Power Sprinter, B minus, 40 Conoline, C plus, Diesel Pushing, C minus. Now, I've worked on hundreds of VAMs, but nothing pisses me off quite as much as the Ram Pro Master. Why does it deserve an F tier? Well, from a user perspective, you might think, hmm, this van's nice and comfy to drive. It's nice and wide inside, should be perfect for a conversion. That's true, but from a mechanics perspective, you're looking at a very cheaply built front wheel drive over sized minivan. This engine rarely lasts over 150,000 miles. What's worse is that the engine and transmission are crammed into such a tiny little tight space, a job that should take five minutes can take up to five hours. More on repairability later. Now, why on earth do I put the Sprinter in the super tier? Why is it the only one there? Well, ultimately these VAMs need a tier list of their own given the engine options and configurations that exist even in the US. For now, let me just start by giving you half a dozen reasons why these deserve to be in the super tier. Ultimately, the Sprinter van has the most internal space. They offer the absolute best driving experience. They get the best mileage. They're the most capable off-road, the engines last forever, and they're arguably the most easiest to fix. More on that later. Now, the gas Sprinter shares many of the same benefits with its older diesel brother, with the exception of reliability and good mileage. Now, they have introduced a newer gas Sprinter, which may redeem itself. However, the older gas powered Sprinter, I'm not impressed. Hence, beatier. But if you are looking for reliable gas powered engine, go with the Ford Transit. They have a couple different engine, gas engine options, which they've taken from the Ford F-150. And they've been running them in the F-150 for well over a decade now. So, you think looking at reasonable reliability, reasonable gas mileage. And really, the only downside is I personally hate the way they drive. But here in the US, for a gas powered engine and a van, this is the best you get. So how about the diesel transit? Why is it ranked lower than the gas transit? Well, ultimately, this is a beautiful diesel engine. Arguably, almost as good as the Sprinter diesel engine, the only issues with these are the same modern emissions issues that plague the Sprinter vans in the newer years. The reason why the transit diesel is ranked lower than the Sprinter diesel is because the same modern emissions issues are even tougher to track down and repair on the transit than they are the Sprinter. Here's where we speedrun through the last five. The Nissan NVD Plus drives reasonably well. You can stand up in the back. However, engines more or less face a junk. The Ford Econoline, Chevy Savannah, a lot of different engine options. Most of them are reasonably reliable gas guzzlers. I don't care for them too much. They're fairly short, hard to find. The aftermarket ones with the higher top, most of the time you can't stand up in them. You don't really get great gas mileage. The only thing I'm going for them is that they are usually quite cheap and plentiful. What you will spend making this vehicle nice and drivable, you could likely get a nicer vehicle for that amount. Right. Now comparing that to the other Ford Econoline similar chassis, this one gets an absolute F and it's not the chassis's fault. Simply because the rear RV portion of it is built so incredibly poorly, if you ever deconstruct one of these, you'll see that the interior covers and what not are really what's holding the thing up. The walls you could likely punch through. They're made of the same styrofoam as you get in a cardboard box. The schooly D minus, they get decommissioned after around 12 or 15 years. Usually a lot of city miles. A lot of them do have transmission issues. Some of them can be fairly solid. However, they're not the best. They're big. They're heavy, low gas mileage. I'm not a fan of converting these simply because you usually can't take them to many places after. You stick out like a sore thumb and a converted school bus. So ultimately, likely the best to avoid. Not terrible from a reliability standpoint, if you get the right drivetrain. Last but not least, the diesel pusher. The unique thing about this one is you can find them fairly cheap with still a reliable drivetrain. So if you find something with maybe a Cummins or a Duramax paired with an Allison transmission, something along those lines, you'll find reasonable reliability. If you are looking to go with the older 90s to early 2000s RV option, go for the diesel pusher. It will be the most reliable of the group. Ultimately, I have shares the same issues with the school buses and that they're generally pretty large. They're not the best for traveling. They're the most controlled living, but not necessarily the best for moving around. You can't fit in any parking spot in any place. So that's why the rating is relatively low.
