Best option for heat retention and leveling is always a plywood subfloor on 2x4s or thinner sleepers- this would make leveling a breeze, but you do sacrifice some ceiling height. 

Guy PM off of BP a month or so ago and that is exactly what happened took title via QCD into a land trust had the sale ready to close but title co.. would not insure .. and then to make matters worse this guy could not get with the seller /  reading between the lines bad blood... 

Not in a million years will they tell you about the blood you're gonna sling.

Rehabbed them with shoddy contractors, my husband, my friends, children who I pay and teach the skills, and lots of blood, sweat, and tears. :-)

Don't spend a bunch of time trying to get blood from a rock. 

She had found out about me through my old lawyer, through the same association I had contacted, and I informed her of my experience and suggested she settle in court, but she wanted blood, so she decided to pursue the charges.

Too rich and competitive for my blood there.

Going into a knife fight is like putting your hand through a fan blade and trying to pull it out without getting touched.So we train with the fact in mind that we do not want to get cut but accept the fact you will most likely get cut and that you have to get over it.There will be a person that lives and that dies and you have to make sure you are the one that lives.Of course if you can escape a situation without altercation or contact that is best and to talk them down.With the knife training you can also use red marker or a red paint that looks like blood etc.The goal is to get you seeing red (blood) without going into shock and shutting down.External weapons are good but your body is the best defense as it never leaves you.If you train with a gun or a weapon all the time but are in a venue where they do not allow those items then you are at a disadvantage.You can always look for items close by to use as weapons.You can also use objects that do not move such as smashing into walls,the ground,through a glass barrier etc.I have been attacked in the past so I know what it feels like.It happened a long time ago by a gang at the beach when we were on spring break as teens.It was 3 of us and 12 of them.They were going beach by beach in broad daylight trying to get money for drugs and assaulting people.They were not staying at any hotel so the cops never found them.Luckily I was just bruised and sore a little bit.

That being said, people who call themselves wholesalers can and do go after thinner margins then I will, and they make it up in volume.

My Dad says he spilt blood at the Alamo, he tried jumping over a low rock wall at a parking space out front, fell and skined his chin!
