He made the total $7500 out the door and I was able to get it within 30 miles from my house.
$7500 was my budget but I feel on the fence not getting insulation. And if I want to insulate myself then I have to pull all the stuff they installed back out

The insulation available from the factory is r6 bubble silver type insulation. I plan on putting a 13.5k ac roof mount in it, so my only concern is keeping it cool on hot summer days. The door will be used alot, and I might even have freezor door plastic stripping in it to allow people in and out quick... So I am not sure if insualtion would make much difference. My outside will be white and tan, so no black. Anyways insulation is $500 for the r6 bubble type, what are your thoughts on adding it or skipping it or doing it myself later.
The plans for the trailer are
I am adding a 100ah 12volt batter with 40 amp powersupply converter a pd9245cv installed. I am going to do a fuse box as well all in the front. Tons of led strip accent lighting with music control and then also some 12v dome lights. My plan is if I have no electric I can use the 12v system to charge my cars and run some lights maybe a small stereo. I also have a small inverter if I want to run a radio or something off of.
I will be installing the ac and I have enough generator to power everything 5400watts so if needed we will run the generator. The ac will be added later but I figured that can be installed without taking all the walls out.
I am going to install 16' x 30" workbench along the drivers side wall for 3-4 guys to pit out of, and various peg board and shelving on the walls.
There will be a cabinet built in the front v with a simple sink into a 5 gallon bucket and a water tank on the counter till I can figure out a simple faucet with a 5-10 gallon resevior.
I might install some wall mounted bunk beds. eventually, there will be a tv, an xbox one, and killer sound system that should rattle the walls off. there will be a mini fridge and some type of cabinent in the front to hold some household goods all built into the V nose.
I have alot of 12v wiring to do, so some access behind the walls would be nice. I guess my question is getting wood walls and skipping the vinyl, but having the insulation added behind the walls. to kinda offset the cost. but I like that factory fit and finish on the walls and ceiling... I am also thinking about adding to the budget if I must to put the insulation in it... But I do have more time than money to be able to add foam insulation and finishing the walls myself. I am all over the place here....
Let me know your guys thoughts, pics and design plans will get added as things progress, I want this to be the most intense pit trailer around. I really don't know how to do things any other way, lol
Thanks for reading your input is appreciated.
