Tiny homes can have holding tanks; it just depends upon how they are built. Many now go with composting toilets as they are meant for off-grid use. To my knowledge, tiny homes are also required to meet the height requirements of normal RVs since they too, must be road legal to travel down the highways without special permits. I have personally never heard of an RV park having a height restriction, so that's a new one for me.
Thanks, Linda, I too think tiny homes are just as popular as ever; they are just morphing into a different use than a typical RV and by a different crowd than the typical RVer. These are young people who are trying to live minimally and own something without a huge mortgage. They like the fact that once they own it, it can be moved if necessary, if a situation requires a move, unlike a stationary house.
A local couple who looked at it are actually older. They own and travel in a motorhome; own a stationary home, and several pieces of property "up north". They are giving thought to building a tiny home to place on one of those properties, as some close friends of theirs have done, who rave about how nice it is as "a cabin on the lake". Since it is classified as an RV, it does not add to the property tax basis on those properties like a stick built cabin would and can be left there for them to enjoy seasonally.
We're just hopeful this rig can be of use to someone who has the vision to reinvent her, LOL, before we totally destroy the body and turn it into a flat bed trailer. 🤪
