I installed my Anderson hitch in 15 minutes using the factory puck system.

putting holes in your frame is something you want to avoid if possible.
The little extra cost saved me from headaches of the other install.

High installation costs
Cost of 5th Wheel Hitch? We ordered a Grand Design 28BH that is supposed to arrive next month and we're in the process of getting a hitch put in the back of our Ram 2500.
I ended up shopping around and found a place that will install an Anderson hitch for around $2100.
That seems really expensive.

Core Power Plays

The specs and strengths that make it shine.
Discussion about various hitch brands and their features
Go with B&W. You shouldn’t have much to worry about.
I got tired of that.
Discussion about preferred hitch systems for towing
I can't find much information online about the pros and cons of both options.
the install is a good bit cheaper and easier.
But rails are just fine.
Rails will always catch when loading stuff in / out of your bed.
Discussion on hitch compatibility with F-350
Can I just buy any fifth wheel hitch?

Hidden Hero Hacks

Unexpected tricks and side‑door uses you’ll love.
Discussion about using gooseneck adapters for fifth wheel trailers
Anyone used these before? Good experiences, bad, or otherwise?
I love mine! And it’s validated by Lippert.
It seems to work fine.
they really are hard on frames and no manufacturer warranties them.

Buyer’s Cheat Sheet

What to check before you click ‘Add to Cart.’
Discussion about vehicle capabilities for towing fifth wheels
They want to sell us one from inventory but they cannot find one with the packages we want.
I’d spend the extra $1,500 and get an F-350 SRW.
I think that means a Winnebago Minnie 2405RG that is 26 and 3/4 when hooked up to the truck is really only going to be about 23 ft longer than the truck.
5th wheel tows so much better than a bumper pull.
Discussion about the need for a dually for towing
Do I need a 3500 dually or will a SRW be fine? Everyone I’ve asked says something different.
You’ll probably be happier with a dually though.
If you’re going to travel with it, I’d go straight for a duality just for the comfort level.
Fuck yea you need a dually. Don’t even think about towing that with a single.
Discussion about towing capacities and vehicle suitability
My uncle told me very sheepishly that I had made an extremely expensive mistake.
Towing capacity usually doesn't mean much as the payload will always be exceeded before pulling power.
You need a bigger truck.
A 2500 is not the right tool for a big 5th wheel or a bed camper.
Confusion over hitch fitment compatibility
So now idk if I need rails or if I can find a model that drops right into it or what any advice is appreciated.
PITA I’ve ordered hundreds of car/truck parts but the RV world is a different game.
Challenges with installation processes
It’s a several hour deal, but pretty straight forward.
Discussion about 1/2 ton trucks and their towing capacity
Look, I know the consensus is that “1/2 ton towable” 5th wheel is a lie.
If you want a full size 5th wheel, definitely opt for a 3/4 ton, even the smaller ones will be so much more pleasant to tow.
Just go 3/4 ton. You can pull a larger range of campers safely.
You will question your life choices when a semi passes you or the wind kicks up.
Concerns over the compatibility of larger fifth wheels with 1/2 ton trucks
It pulls it beautifully and without any extra stress on it.
General advice on choosing the right truck for towing fifth wheels
I don't believe it without seeing the 'Tire and loading' sticker on the door jamb.
Variability in hitch costs based on type and installation
my price was about $2700 for everything.
Discussion about purchasing trucks without factory-installed hitches
5th wheels are so much nicer than the travel trailers we've seen.
If you find a used truck with a hitch, you'll know that the truck was previously used as a tow vehicle, no questions asked.
Advice on gaining RV towing experience before committing
Because '34 ft 5th wheel is a big beast and you'll be sized out of many places like the national parks.

Cautionary Callouts

Know the pitfalls before they catch you off guard.
Discussion about the importance of checking kingpin locking mechanism
Let’s not get lazy and have our trailer fall off on the interstate at 65 mph.
Seems the new breed get their rocks off trying to fuck other truck drivers over.
Speaking from experience.
Discussion about fifth wheel vs gooseneck hitch
Is this a Fifth Wheel hitch or a Gooseneck hitch?
That’s a gooseneck, but I kinda looks like the adapter is still on there?
Friends of mine are saying it's obviously a gooseneck.
Experiences shared about towing with different truck models
Pulls beautiful at 80 (I15 Utah). I only pull at 70 max these days though.. older and smarter.
Concerns over installation and safety of gooseneck adapters
I'm not feeling too confident with our installation.
Still feels sketchy.
Not sketch at all and the only gooseneck hitch supported by the frame manufacturer lippert.
Discussion about RV security concerns
Fifth-Wheel Security? [deleted]
I’m a full-timer who sometimes camps in sketchy areas and/or leaves my home parked unattended at trailheads, so I’ve spent more time then many thinking about RV security.
If you want to be more secure, you may want to replace the locks.
RV's are held together with staples and bubblegum.
Concerns about varying hitch brands and designs
I was really surprised when I looked up the retail.
Experiences with poorly installed aftermarket hitches
I got mine cheap because of the crappy previous hitch install. I did it so I can get in and tow my house with absolute minimum fuss.
