Double check me on this but I think both of those might be narrow 96" (8') wide units not the 102" (8'6") units. So measure your storage area if you are trying to get the ATVs in side by side.
To me it doesn't matter who you buy it from, you need to do a detailed PDI (your own not the one the dealer does) so you can really test out each feature & function, before you sign any purchase papers. Once you sign the paper work you own it and then it's you, working through the dealer (or another service dealer) getting any work done and approved by the manufacturer. If you find problems first, the dealer will get things fixed so they can sell that unit (fast).
You can find many PDI check lists on the web, I recommend the Tom Boles' Check list available
here. I think the only thing missing is to test any electric bed and the fuel station ability to pump out gas - for that bring along 2-5 gallons of gas and test it. Check to see if the gas coming out is discolored while your at it.
