Woah woah woah.....slow down. Lol
Ok, there are a lot of things you need to factor in before worrying about things like TVs and after market airride.
1. Where are you planning on getting your freight? Are you planning on trying to use load boards or contracting your Vans to another company who has their own authority? What about insurance?
2. Where are you going to be getting your drivers? Are they experienced? Do you already have them lined up? Are you going to be able to retain them?
3. How much are you going to need to gross per month per van, to be able to pay your drivers, maintenance your vans, and pay for other costs? The market is in the toilet right now. Rates are not good. So realistically, do you think it would be the best time to start up a business right now with how uncertain and poor the markets are?
After all that, there is really no cheaper or more convenient way to have AC power....than a generator. You can usually pick up a compact generator with the necessary load requirements for $600-800 per. It will run AC in the summer time and can run heat in the winter. (however in the winter I found that using a buddy heater with a 20 lb propane tank was the most cost-effective, and convenient way). I have not known anyone to install aftermarket air ride on their vans. Because most freight doesn't require it. Best things to have is a van that can carry three pallets, plenty of straps and blankets.
