TL/DR: I don't trust my grill after years in storage and want to know how I can be sure I don't light it and blow myself up.
Several years ago while living in Denver I was given a house warming present from my now-passed away mother: A nice propane grill. I used it almost year around, running probably 4-6 large propane bottles through it.
Then I moved to Texas. The grill went into a storage container (PackRat/Pod container), and was driven down to Texas, where it sat in storage for two years. When we were able to move into a house, I got it out of storage and put it on my back covered patio. The grill also has a black cover like you buy to keep the rain and snow out.
However, now the grill just sits on my back porch, begging to be used. I LOVE to grill, I LOVE grilled food - especially veggies like squash and asparagus. Trouble is, I can't bring myself to trusting the grill. It was jostled about a lot while on the way here, experienced below freezing temps while in the container, and hasn't been used in several years.
I assume I need to check the metal hoses that run to each element from off of the main line that goes into the propane tank. Also I know I should check that main line. What am I looking for? It is better to just try to replace all the hoses/cables? The auto-light feature doesn't work anymore, so before it went into storage I would use either a lot or one of those long-nosed lighters. I haven't bought a new propane tank yet either.
If the grill didn't have sentimental value (and wasn't so nice, or at least nice to me) I would probably get rid of it and just buy a new one, but my mom bought it for me before she died, and grilling has always been one of our connections (I'm from Texas, what did you expect?)

I am thinking I may disassemble the whole thing down to its parts and check and clean each piece, including the metal grills themselves, the metal tub that caught 5 years worth of dripping grease from a thousand steaks, burgers, and brats, but without knowing what to look out for, I don't trust the outcome. I worry about everything in life, so it isn't a stretch to worry about microscopic fractures in the cables that send me to the local burn ward.
Anyway, I'll try to post some pics tomorrow. Today it is about to storm, so I'm going to stay in.
Thanks everyone!
