WELL ACTUALLY I DON'T SEE BUNKS VERY OFTEN FOR AN ALUMINUM BOAT. I HAVE BUNKS ON MY TRAILER WHICH HOLDS A LUND BUT IT IS 20.5 FT LONG. THE ONLY TIME THAT I SEE BUNKS FOR AN ALUMINUM BOAT IT IS USUALLY A 20 FOOTER (2025). I THINK THE EXPLANATION IS AS SIMPLE AS......THE LARGER BOAT WEIGHS MORE, THEN YOU HAVE MORE SURFACE AREA OF THE BOAT BEING SUPPORTED BY BUNK. IF IS WAS A ROLLER TRAILER YOU ONLY HAVE A COUPLE SQUARE INCHES OF SUPPORT EVERY FEW FEET.

I am positive is just a cost issue for up to a certain size.

Also market trend is a factor.

Bunks hold your boat on trailer better, there is no risk to roll it back off, and has slightly better support.

Rollers will let you roll off your boat even in shallow waters, they are easier to load also, but give you slightly less support then (good) bunk trailers.

Price is a factor, bunks are just carpeted wood 2"x4" or 2"x6" on top of a frame, the better build have more supports for bunks so they don't flex much.

Rollers have to have all the components (rollers, subframe, and supports) mounted to the trailer frame, thus a considerable price difference.

Choice is personal and depends on use, I like bunk trailers, when my boat is on the trailer, it's on it, not a chance she's gonna come off. Many people likes rollers so they can load/umload boat easier.

One of the most common accident with boats is to be dropped on ground at landing since they rolled off trailer.

Roller trailer is a trend locally, many other areas don't even consider them.

There are also big boat trailers with rollers, but almost extinct anymore.

I've had roller trailers on boats up to 25' and wouldn't go any other way.

The support issue of bunks being better I don't buy.

Yes the bunks have more surface area but the support is only under the brackets or mounts.

With either type trailer, poor alignment of bunks or rollers can damage your hull.

I prefer the rollers because of ease loading and unloading and quite often I use lake accesses that are very shallow where pushing a boat off bunks would be impossible.

There are those that prefer bunks for power loading, although I haven't seen a access where power loading is prohibited in my area, I know there are some. Whats happens is the props wash scours out a hole. If theres a pad at that launch it leaves a heck of a drop off.

Down here I can't remember ever seeing a trailer with rollers on it. I think Valv is correct about it being a local thing! When I come up north almost all I see is roller trailers, and I have never seen a boat fall off the trailer!

I just brought this up because when I was at the new Cabela's looking at the Alumacraft boats I noticed that most of the trailers where some brand I hadn't heard of before and bunks. I just figured that the trailer they use is a major factor in keeping the cost down.

Mnfishinguy, I like your signature. I really had a kick since in my house we have a small sign hanging that says:

I'm originally from KY where all the boats are glass or lightweight metal john boats. The ramps are paved and some are 5 and 6 lanes wide and lead to deep water. I don't belive I ever saw a roller trailer down there. Up here in northern MN I would bet that only 10% are paved and have deep access. An improved ramp at most landings is some concrete at the waters edge. I have an 18 foot boat and there is no way that I could use a bunk trailer at most of the landings I use. I doubt that I would be able to drive on either. As in most cases with any type of equipment it depends on where and how you are going to use it. I've heard that bunks won't damage the hull of the boat, but I've got 25 years of hauling 7 different boats with a roller trailer and have never damaged a hull.

I have a 16.5 foot fiberglass bass boat with a bunk trailer. I have yet to have a problem getting it into the water on any lake, although most lakes I fish are in southern minnesota. Unloading it takes as long as it takes to back the truck up and then pull the truck out, as long as you have someone in the boat who can drive it. Loading it we do power load, could literally load the boat and have it out of the water in probably 10 seconds if we tried at it. The longest it has ever taken us to load the boat and get it out of the water is probably 2 minutes on 2-3 foot swells on Mille Lacs.

    • It’s done automatically.  You might need an actual person to clear that log in stuff up.   Trash your laptop history if you haven’t tried that already.
    • 😂 yea pretty amazing how b o o b i e s gets flagged, but they can't respond or tell me why I  can't get logged in here on my laptop but I can on my cellular  😪
    • I grilled some brats yesterday, maybe next weekend will the next round...  
    • You got word censored cuz you said        B o o b ies….. haha.   Yeah, no… grilling is on hiatus for a bit.
    • Chicken mine,  melded in Mccormick poultry seasoning for 24 hours.  Grill will get a break till the frigid temps go away!
    • we had some nice weather yesterday and this conundrum was driving me crazy  so I drove up to the house to take another look. I got a bunch of goodies via ups yesterday (cables,  winch ratchet parts, handles, leaf springs etc).   I wanted to make sure the new leaf springs I got fit. I got everything laid out and ready to go. Will be busy this weekend with kids stuff and too cold to fish anyway, but I will try to get back up there again next weekend and get it done. I don't think it will be bad once I get it lifted up.    For anyone in the google verse, the leaf springs are 4 leafs and measure 25 1/4" eye  to eye per Yetti. I didnt want to pay their markup so just got something else comparable rated for the same weight.   I am a first time wheel house owner, this is all new to me. My house didn't come with any handles for the rear cables? I was told this week by someone in the industry that cordless drills do not have enough brake to lower it slow enough and it can damage the cables and the ratchets in the winches.  I put on a handle last night and it is 100% better than using a drill, unfortatenly I found out the hard way lol and will only use the ICNutz to raise the house now.
    • I haven’t done any leaf springs for a long time and I can’t completely see the connections in your pics BUT I I’d be rounding up: PB Blaster, torch, 3 lb hammer, chisel, cut off tool, breaker bar, Jack stands or blocks.   This kind of stuff usually isn’t the easiest.   I would think you would be able to get at what you need by keeping the house up with Jack stands and getting the pressure off that suspension, then attack the hardware.  But again, I don’t feel like I can see everything going on there.
    • reviving an old thread due to running into the same issue with the same year of house. not expecting anything from yetti and I already have replacement parts ordered and on the way.   I am looking for some input or feedback on how to replace the leaf springs themselves.    If I jack the house up and remove the tire, is it possible to pivot the axel assembly low enough to get to the other end of the leaf spring and remove that one bolt?   Or do I have to remove the entire pivot arm to get to it? Then I also have to factor in brake wire as well then. What a mess   My house is currently an hour away from my home at a relatives, going to go back up and look it over again and try to figure out a game plan.           Above pic is with house lowered on ice, the other end of that leaf is what I need to get to.   above pic is side that middle bolt broke and bottom 2 leafs fell out here is other side that didnt break but you can see bottom half of leaf already did but atleast bolt is still in there here is hub assembly in my garage with house lowered and tires off when I put new tires on it a couple months ago. hopefully I can raise house high enough that it can drop down far enough and not snap brake cable there so I can get to that other end of the leaf spring.
