We have been thru Yuma many times but this is the first time we've spent any length of time here. Being every place is different, here is my take of what would of been nice to know before arriving.
As far as the RV fix-it guys. I was in
http://www.rvconnectionparts.com/ a couple times over the last week. Seems every time I go there, RV techs buying parts to fix RV's for somebody. Many RV tech's to choose from.
I have been asked if I'm paying cash or credit card more times than I've been asked in the last 5 years for some reason. Maybe the services I'm seeking? RV wash guys, RV tech's, A/C auto garage etc. So know where to your ATM is in advance if you don't like carrying lots of cash.
Fry's on 24th usually has the best fuel prices IMO. And use your Kroger fuel points if you have any. But it is not big rig friendly if your in Class A. And buy your ice at Fry's if you need any. Walmart's ice is bad IMO, when it melts there's a scum on bottom of glass. (make sure your the park you choose has R/O water or some Yuma vets have a built in R/O system in there RV for drinking). IMO Walmart has better produce than Fry's. Several RV's also overnight there, if that's your thing (on Pacific anyways). Vacancy signs beginning to show up at different RV parks I pass. The people leaving our park have been here many months and are talking about the heat, (86 today) and taxes done and good weather back home (of course others not so lucky and just moving to cooler temps at higher elevations, if the heat bothers them).
A lot of tax prepares have signs out.
There is more RV parts and stuff at one place than I've ever seen at
http://www.arizonamkt.com/ Watch what days they are open. Thursday and Fri free and less crowded than on weekends. Weekends they also charge a whole fifty cents a head to get in.:)
Many "Yuman"s" get up and get going before the chickens even think about it. Myself on the other hand, it is now 12:14 AM and I'm going to sleep.
Hope this helps
