I suspect prices will go up because they just lost one of their nice RV parks to development - Bernardo Shores in Imperial Beach. Hated to see that one go!
To get lower prices and more space, you'll likely need to look east and north of the city. One other thing you might try - search from time to time on the San Diego Craigslist site. Under "housing" sometimes private parties will list RV pads for rent on their property. I looked at a couple a few year ago but the locations just did not work for me.
Some smaller, off the beaten track RV parks sometimes advertise there as well.
For peace of mind and safety, I would change them. Why let a blowout or two ruin a nice travel season? My Dad suffered many blowouts over the years on motorhomes, trailers and boat trailers. He seemed to think as long as the looked OK, no problem. When they would blow out, he would blame the engineers. I've NEVER had a blowout and will not run a tire longer than 10 years.
I've found many posts in the forums about issues on DPs where the parking brake alarm does not silence even after the air parking brake has been released. Mine was doing this. It would beep for awhile then stop, and maybe start up again for no apparent reason.
Others have commented their problem was a defective sensor on the switch. I finally got brave and pulled the panel off the driver side console to diagnose the issue. It quickly became obvious to me that the parking brake switch itself was loose. Tried to tighten, but one of the screws was stripped.
So it seems that all the downward pressure to release the parking brake caused the threads to strip and the switch became more and more loose. Turns out the machine screws go all the way through the flange on the switch so I just got some nuts to back them up and got the switch firmly seated.
SO glad to have this resolved. I just never noticed that the switch was loose - I don't tend to look at it when I am activating or releasing it.
They were banned in National Parks last year.
And here is an article about things going on in specific states:
Or... another way to look at it:
It is common practice for Class A drivers to "wave" as they meet on highways, but I don't think those driving a Class A will wave at someone pulling the fanciest of fifth wheels.
Also, I suspect there have been times when a CEO out for a ride on his "hog" has exchanged the down-low peace sign with a gang member on his hog, but I bet if they met with the CEO in his Mercedes it would be a different matter.
Bottom line, people are pack animals!
While not directly answering your question, a couple of years ago I used Creative Coach in Lakeland to install my residential fridge, add valances over my aftermarket MCD cockpit shades and also trim out my upgraded HDTVs.
Great quality work, but it ain't cheap.
