In MOST cases I would agree. With the plumbing lines so small in RV's it really does not matter.
If you want a hose that will last you forever and is easy to coil in cold weather and it does NOT get fat. I highly suggest logging into "rvfilterstore.com" their hoses and end connections are top quality. Don't waste your time looking unless you are willing to part with your $$$. I purchased three different lengths. Been full timing with them for over two years, still are in perfect condition.
They have high quality Watts water regulators.
