Walleyehooker -
I own a 2011 8x16 IC with a beavertail and rubber flooring. There's a lot of griping on the boards about them but keep in mind, there are also more IC's out there than any other maker by a wide margin.
It's had it's share of issues, but nothing too overwhelming. I'll admit, I take pride in everything I own and am a bit of a perfectionist as I like my gear to work when I get out on the lake and I like it to look good. I often sell my used equipment to my buddies because they know I take care of stuff.
In my experience, as long as you do preventative maintenance every year, you'll avoid most major headaches. This past season, I did have to have one of the trailer brakes re-wired and had to replace the co-ax cable to the dish (about $800 by the time things were diagnosed and completed). If IC built it with a (ground box?) in the V, I'm told this would've been a simple/cheap fix, but of course, they didn't, so all wiring had to be replaced.
Annually, I like to:
Grease all pivot points (I had an extra zerk installed on each side near the pivot point several years ago for good measure)
Re-pack the bearings (I did this for the first time myself, a few weeks ago, pretty easy; although they should probably just build them with bearing buddies IMO)
Sand down any rust spots on the frame and repaint (I use a 3M cordless drill brush attachment and some anti-rust primer and spray paint). Keeps the frame looking great and only takes 3 hours or so while enjoying a few barley pops.
Replaced the chrome hub and lug nuts for the first time as they had rust developing
Spray the beavertail surround with silicon to avoid sticking and keep the foam/rubber from cracking.
Other larger projects I've had off the top of my head include:
Replaced flimsy tongue lift with heavy duty crank lift (shop welded it on)
Replaced steel cable with stainless steel cable several years ago (I have crank up/down). This should be standard but I suppose stainless costs more.
Over several years, I've replaced all screws (probably 300+), internal (mostly hole cover surrounds) and external, with stainless screws. Again, this should be OEM but I suppose stainless are more expensive, which is pathetic but oh well.
After this coming season, I'll probably replace the tires for the first time.
Not sure any of this will help you, but thought I'd share my experiences based on the past 5 seasons. I will say, if/when I buy a new one, I'll probably look at Yetti the hardest.
The lighter weight (about 1,000 lbs lighter I believe in an 8x16) along with never dealing with rust again, are very attractive. That being said, I'll also be looking at a $8-$10k price premium, so we'll see.
I am kind of curious what my IC would go for (I'm definitely not selling it this year but maybe next). Would love people's input just for curiosity.
