Hey Marv! I know I am a little late to the conversation but hopefully this helps someone out there.
As far as purchasing a generator for camping is concerned, there are two main factors to consider. The first is how much power you will require and the second is noise emissions.
POWER: If you do not require your generator to power a 13,500 BTU AC unit then something around the 2000W range should power most of your appliances without worry (coffee makers, hair dryers, CD players, laptop/phone charging etc). If you do require something that can power an AC unit on an RV you should be looking in the 3000W and above range for a 13,500 BTU unit. You can check out this
usage chart that lists a number of common appliances and their power requirements. Add the totals of the appliances you plan on running in conjunction with one another and you will have your power requirement.
NOISE: No one wants their campsite to sound like a construction zone. If you are looking for quiet portable power you are in the market for an INVERTER generator (as opposed to a conventional generator). Inverters also produce a "cleaner" power source that is suitable for sensitive electronics such as laptops and smartphones. The inverting process produces a smoother sine wave that will not damage the microprocessors within these electronics.
Many people swear by Honda's and Yamaha's and they are the industry leaders when it comes to inverter generators BUT there are many alternative companies (ie Champion, WEN, Briggs and Stratton) putting forth very competitive products at a lesser price that merit consideration when shopping around for a generator.
I found this website to be extremely helpful when deciding which generator best suits your needs;
http://www.quietpowergenerators.com/The "inverters vs generators" page is very insightful and arms you with the knowledge necessary to make an educated purchase. They also have detailed reviews of the latest and best selling inverter generators on the market.
I hope this helps Marv! Happy camping and all the best,
Dave
