The only issue I see is the space? You would need to store 12 to 15 six packs in order to have beer to drink and empty bottles to fill/age and then drink. Plus room for fermenter and brewing equipment/supplies. I would use kits and then only have a few on hand.
If you full time maybe you could do it depending on your rig/trailer. I take beer with me for a couple weeks trip but usually only have one or two beers a day so no more than a 24. After two weeks I buy beer. There are now many good brewers in the country, 10 years ago brewing your own would have been more of a necessity to have good beer.
