It's some thing like 1/2-2/3 of our legislators iirc.

I'm not saying these are not real problems, but people who rent houses and apartments from landlords face similar problems with rent increases and nothing being fixed. There is an alarming lack of code enforcement and insufficient housing code in the first place, and none of it is acceptable, whether you rent a residence or a lot. There is zero regulation at all on how much rent can increase so it's good, at least, that there is a cap even if they play the game of increasing just enough that you can't do anything about it. Just want to point out that a $20/not quite 6% increase on the lot rent alone is a pretty minimal overall cost of housing increase compared to what is legal and what has become incredibly common over the last couple of years. Let's just assume a total monthly payment between lot rent and mortgage of $1000 to make the math easy. $20 more is 2%. Cost of renting in some areas has gone up 50% or more with literally nothing stoppinglandlords from whatever increase they want. A 6% increase on $1000 rent would be $60 - so at least it is "only" lot rent that goes up by that much, and at least it can be contested if over 8%. I personally know several people who have been renting whose rent went up by hundreds of dollars and significantly more than 6%. Again, I'm not saying this is not a real problem, and I'm not saying it's insigificiant, but I hope you can see that having at least a little bit of protection in that way is good and something that needs to be fought for more broadly. Someone paying $1000 whose rent increases by 50% is a little bit more screwed than someone whose total housing payment is going up by $30 because only a portion of their total cost can increase, and only by a certain percent. No doubt if they could, they'd double that lot rent, just like landlords increasing their rental costs by hundreds.

As someone who faced housing instability for years while renting and now has a CHT home, I absolutely support better regulation on how people are able to profit from owning land other people live on, and that includes both traditional renting and trailer park lot rent. We need some serious housing reform, but dividing renters of different kinds isn't the solution. A relatively small percentage of people own trailer parks on rented lots vs other types of housing (renting, living in an owned home on owned land, resident-owned trailer parks). Maybe advocating for rent control of all kinds, with a broader base of people to fight for those changes, would be helpful.

For what it's worth, Darn Tough did send a couple thousand pairs (or maybe it was a few thousand pounds?) of seconds months ago if I am remembering correctly.
