Do you get a good enough seal on the buckets to not lose water during transport? How do you plan to get the water transferred to your RV? Which containers would make that easier and also allow you to run and get more water if necessary? If you are going to use a water pump to get the water into your RV, it would probably be less hassle with the larger tank. If you are manually transferring, it probably doesn't make much difference since you would be filling a smaller container from the large one anyway to pour it in the RV.
Would you ever be in this position of needing added water in the future and which method would be easier for you to store for future use? The large tank would definitely take up more room than 13 nested buckets.
ALL easily solved by using 7 gal Aquatainers - inexpensive, light weight, large screw on main cap and screw on vent cap which both seal completely, cube shaped so they store efficiently, and made of food grade plastic. I've been using a set of 4 for years now, carrying them in the back of my truck where they're readily accessible anytime, sometimes I carry another 4 for grey water disposal but there's no reason at all I couldn't carry 8 or 12 or whatever number I wanted. Normally I just fill them at the campground as needed but early or late in the season when campground facilities may be closed I fill them up at home. At ~ 60 lbs I could lift a full Aquatainer in order to pour water into the trailer's gravity fill but because I transfer water in quantity I instead use a 12 vdc potable water pump to do the job. When not camping the Aquatainers sit on a shelf in my garage whereas I wouldn't have anywhere at all I could store a single large tank.
