Thank you all for your replies. There are lots of good answers for a comprehensive list of tools.
However, the question is, and I'll rephrase it, are the new rv's, not the old rv's, all metric? Of course I realize the older rv's are pretty much going to be standard ASE fractional sizes. But with purchasing a new, or just a couple year old rv, was just wanting to know if everything, like everything else now in life, is metric sized. If everything now a days is pretty much metric, one can save weight and space by not carrying any standard fractional tools.
This rv purchase for my friend will not be a huge rv, it will be a small or no more than medium size trailer, at least for the time being.
@@@@ OH, and by the way, how many carry a grease gun and use it often enough to justify the space it requires, as well as being a bit messy to store after using? @@@@
Space is an issue, as always, so we just want to get 1 or 2, possibly 3, normal size carry around tote type tool boxes with a basic set of tools that can handle most any easy repairs. Big repairs will be left to professionals.
So it sounds as if it will be best to stock both metric and SAE standard fractional tools. So I will recommend to him to get metric and standard 1/4" drive and 3/8" drive metric socket sets and a normal size metric and standard open end-box end wrench set.
Of course he will have the other normal hand tools, as well as some electric and maybe a few plumbing tools and other things one might usually needs around the house.
We want to keep this total lot of tools under 100 pounds and no more than 2, possible 3 boxes to store them in.
If this was a big diesel pusher rv with a lot of under storage available I'm sure he could bring a larger selection of tools as well as an assortment of supplies, fasteners, misc parts, etc etc etc.
Thank you all for your time and effort in replying, there are lots of good suggestions you've made.
