All you have to do is swith around your jack and put a spare tire carrier on the oppo side of your boat winch and jack. There is plenty of room there. I did this and was still able to use my swing tounge. All those tires should work. I put some large tires on my trailer when i drove from washington to oklahoma because the boat(full of my things) weighed close to 5000lbs. Of course I burned up the transmission in my murano, but that is beside the point. haha. I cut half the metal brace off under the finder just to make sure there was plenty of clearance. also raised the fender about 1 inch for clearance. The boat pulled way better with bigger tires. This is the only pic I could find of the spare tire position and the larger wheels.
take the two stock speakers out and get 4 polk audio db651's. These speakers have been praised by everyone everywhere and are marine grade. replace the two stock ones and put two more up in the bow like the 2010's. I would put the amp in the glove box and a sub either by the passenger's feet or loose one of your under the seat coolers in the back and replace it with a sub. Go with a name brand amp because the cheap ones are nothing but trouble and produce way too much heat. For the extra battery there is plenty of space right by the stock for one more.
You didn't mention tower speakers. If you do get any tower speakers don't waste your money on anything but hlcd speakers. Wetsounds or exile is the only way to go there unless you only want them up there for looks.
If you ever have any questions on this boat just ask. I pretty much know this boat inside and out and I live in OKC.
Vacuhold boat cover for 18' boat. This cover is a top of the line aftermarket cover
Sur Last® Fabric with superior UV resistance and strength.

What does all this mean?
This cover is high quality and made from Sur Last® Solution Dyed polyester which is made here in the USA by Glen Raven Mills, the manufacturer of Sunbrella®. It is a non-abrasive, water and UV resistant fabric. When you team it up with the vacu-hold system, a rubbery/plastic vent that as the air flows over it, pulls the air out of the cover and sucks it tight to the boat. This keeps it from flapping in the wind and rubbing your boat. It comes with a pooling pole system that tents your cover to keep water from pooling water and leaking. It has the ratchet boot assembly at the bottom that makes it easy to tie down and stay on. It has rubberized cleat reinforcements that won't tare, and a storage bag.
This cover is one year old and I dont have the boat to put it on anymore. I also have a large piece of matching fabric if you ever have any tears. First come first serve. Cash only. $200obo
For those out there wondering....yes it is possible. I have the clallenger 180 and surfed behind it this weekend without a rope and i am a beginner wake surfer. I had one 750 in the back seat/ floorboard corner with a 350 on top of that. another 350 under the the driver or passenger floorboard and another 350 in the bow. what sucks is we have a goofy rider and a regular rider so they had to be switched each time the other person rode. We kept the speed at about 12 to 13 on our seadoo guage. We also has a driver and one other passenger when riding so either 2 people on one side or 1 and 1.
After we were done surfing, we tried wakeboarding with all the weight in the midline of the boat. I was unsure of the boat being able to pull all the weight and a rider out of the water but it did just fine, just a little longer to get up to speed and you had to give it full throtle to make a turn and keep the 25 mph speed. Im pretty sure my speedometer is off on the high side. anyways the wake is the best ive ever seen behind my boat. I am very pleased to board behind my boat now. The only issue is space now. Once you get the desired amount of wight in the boat there is really no where to sit.
Has anyone ever though of doing this to their boat. The pic shown is just a removable bench seat. You can always put it back to stock. Another thought I had is building a bigger sunpad on top of the rear storage compartments and engine bay. It would have to come in three sections to maintain access to storage and engine. I think both of these things could be done pretty easy. A few hundred bucks for upohlstry work. Thoughts?
So after wakeboarding about 10 times this spring and trying different places for fat sacs, this is what i found to work the best. I have two fat sacs in the bottom under the cup holders which hold about 250 a piece. They are 350 sacs but the space only allows for about 250. Add a 350 sac to the ski locker. If you have two people on the boat fill it all the way up. If you have 3-4 just fill about half way. This puts out an impressive wake(for a jet boat). We have been able to do back rolls, 360's etc. Don't let any body tell you you cant wakeboard behind this thing. My tower post is between the driver seats and the back seats and we use any where from 70 to 75' of line. Best speed is about 25-26 mph( which is probably actually 23-24 mph). The engine sputters a little out of the hole but does fine. All the wakeboarders are around 170-210 lbs. If you have different people equipment you can adjust accordingly. Also added hydro turf to the back of the boat, a must for wakeboarding. I am so pleased with this boat now.
