The 60xt stays on. The 60a has a tab that makes it much more convenient to take off, but it will also catch on hair or meat and slide off while using it...nothing like searching in a rear quarter for a lost scalpel.
We have built many, as stated you need a thermal break and vent your heat source to the outside. It really is that simple. An RV furnace will work very well, but does require 12v and LP.
I prefer a lid, it is nice to put things in I need quickly or things I don't want bloody on a pack out. It also allows a cleaner and tighter set up, I'm not familiar with a lid flopping around at all.
There are very few extended warranty plans that are worth much in the RV industry, and in my opinion none if purchased for an RV that is over 3 years old. Typically, if it pays 75 cents on the dollar, it is considered a top tier plan. Even these will have a list of exclusions included, but not...
Being in the RV business I am not particularly a fan of extended warranty plans. Having said that, complaining that the warranty doesn't cover general maintenance when it states it doesn't is hardly a reason to be upset. As to your comments about silicone, I really hope they don't have a EPDM roof.
The Fenix HMR65-T has worked well for me. I don't know if the high/medium/low on flood and spot is perfect, but it certainly is versatile and sure works well. You can always carry a spare battery if needed.
I would second the 18650 styles. Much brighter output, longer run times, and no weight penalty. The Fenix HMR65-T and several Zebra lights have worked well for me.
Having them try them out is definitely the way to go. My wife chose something that wasn't even on my radar.
We did try to stay away from Taurus just due to issues we have seen. Basically, if she saw something that piqued her interest, she tried it out. In the end she is happy enough to carry it...
Nitrile gloves have become common place in my kill kit. Easier to grip things when wet, easier clean up, my dirty hands don't touch the meat, and a minimal weight penalty.
You will see a magistrate, he/she will hear both sides of the case and make a judgment from there. You or the defendant will have 10 days to appeal the judgment if so chosen. Typically, the loser is ordered to pay the court fees, but not always.
