I have a 7.5' x 18' plus 5' V and three 137's can be driven straight in with no hassles, not having to lift tunnels or put blocks under the tracks. I load from the front ramp door and unload out the back. Four sleds will fit in a pinch but it's a driving in and backing in the next type of deal. I only trailer the three Gade's regularly.

As for dirt vehicles, definitely get the 6" of extra height and as with most trailers the issue will be the actual opening of the rear door as to whether a SxS will fit. Four ATV's would be no problem in mine but I only have a SxS and an ATV and as such they fit really easy in there. This size trailer is probably the best all around unless you really need space for more sleds or dirt machines hauled on a regular basis.

If this is for sleds I would forgo the cargo style as they do not have a front ramp door and you have to get a longer trailer overall as most don't have a deep V in the front.

 

Most cargo has a steel frame, where I believe most snowmobile trailers are all aluminum. Lighter and no rust.

 

Mine is the model 2066: http://blizzardmfg.com/index.php/trailers/snowmobile/v-nose-box

The trailer will comfortably fit 4 sleds with room to spare for fuel cans, tools and clothing as well as spare parts. The deck over design eliminates the wheel wells inside the cargo area you have to get over or around when loading or unloading. The only disadvantage to the deckover is the ground to door height is higher making the ramp a bit steeper to drive up or walk up.

The trailer tows easily and tracks well even at turnpike speeds. Very little 'pitching' from front to rear even on bumpy or rough roads.

I did opt for a couple options. Brakes on both axles, spring assist on the front V-nose door, back up lights, a second vent on the roof with Maxi-Vent covers (so I can leave the vents open in any weather) aluminum wheels, spare tire w/ mount and loading lights, and the optional trim on the exterior..

This trailer can be hauled with a 1/2 T. pickup or in my case usually with my 1/2 T. GMC Suburban.

Before I bought this trailer I had a 20' cargo trailer with only a rear door. None of our race sleds have reverse so it was a PITA to unload especially in a crowded pit area. The trailer was much heavier and felt like it when being towed. I sold that trailer to an ATV'r.

Must be a regional thing? Locally both cargo and snowmobile trailers come in both steel and aluminum. :shrug

To the OPs question, as far as fitting things in, except for the height issue (see below) I'll leave that up to the tape measures. What I can add is I went through the same thing - sled trailer or cargo trailer? In the end you need to be honest with yourself on how it's going to be used. While I started out looking for a snowmobile trailer in the end I decided a cargo trailer made more sense for how I'd be using it most. It's been 2-3 years now and if I were doing it all over I wouldn't change a thing.

In the end I bought an aluminum NEO 7x16 (plus the V) cargo trailer with the extra height and radius roof. At the time I didn't own a SxS and didn't think I'd need the extra height. My wife (SMART woman!) said I wasn't getting any younger and someday I might own a SxS. She said "wouldn't it be bad if you bought a SxS and it didn't fit in your new trailer?" She was 100% right. Today I own the SxS and without the extra height it wouldn't fit. 2 Cam Am Outlanders fit in end to end easily too. Snowmobile duty has been it's least use. It's been used as a moving trailer & construction trailer more than anything else.

I'm 100% happy with my choice and 100% happy with the quality of the NEO.

Good luck.

 

I'm waiting on delivery of a 7.5 X 16' +6' V Neo NASX all-sport trailer with an added 6" height. I'll be hauling 2 137" snowmobiles (maybe 3 next year) in the winter and a 4 seat sxs in the other 3 seasons. One big reason I went with the added front ramp is that it doubles my options for loading/unloading - helpful on busy roadsides and tightly packed parking lots. I can haul a little under 5000 lb of whatever I want with this unit so unless I'm hauling heavy construction materials that require 10,000 lb+ GVWR, this one should do fine. I'll rent a heavier one for the very rare occasion I need to haul something that heavy. I've used enclosed cargo trailers for hauling sleds and yes, they definitely get the job done but for my purposes I couldn't see a scenario where the extra door in the front would be a negative so I went for that kind of trailer.

Good luck with your choice!

 

I have a cargo trailer I used for work before I retired and have a Triton Tc 167 for my sleds. Like mentioned before you need to decide what you will be using it for.
I like the fact that my sled trailer is very light and easy to pull and wouldn't want the extra weigh of a similar size cargo trailer. This is partly due to the fact my tow vehicle is a 2019 Chevy Traverse and my previous rig was a 2017 Honda Pilot.

 

Some manufacturer's list length including the v. Some list length by box size and the v becomes bonus area. I prefer box length myself. Get a trailer with box length that will suit your needs, then you have some extra room and won't be cramped. You also may not need a front ramp, but they are handy.

Also ATV capable, I think you have to go extra height and possibly extra width. Make sure you have actual measurements of what you want to fit through the door and check opening on any trailer you consider.

You can also lay out trailer dimensions on ground and try parking stuff in the area. Keep in mind 7' wide trailers are not 7' inside.

 

Probably a minor thing..... A cargo trailer, without the ramp in the vee up front, does not look like a snowmobile trailer. We have to tow a loong way for any snowmobiling and prefer not to have others realize we have snowmobiles inside when we park at motels by the interstate at night.

And I know we are all mighty proud of our snowmobiles. But putting big snowmobile stickers all over the trailer just seems to be a beacon for the wrong types!

 

I'm leaning toward a 7.5 x 18 plus the V NEO brand trailer.

That's what I have. I use the front ramp every trip and even more often when it's parked at home. I also use the fuel doors every trip.

 

Just an FYI - I saw a post earlier in the season that someone bought a cargo or car carrier trailer with a rear drop and a front drop door in the vee. They didn't realize that their sleds were too wide (42") to fit through the front door. Sounds simple but if you aren't buying a snowmobile trailer measure your front door.

 

I wanted a 18" x 7 trailer plus the 5' point with 6'6" height but ended up with a 20 x 7 plus the 5' point with 7' high ceilings. I can drive three 137" in either from the front or the back without doing anything goofy!! The 7'6" wide may not be bad either.

I have the 20 foot plus the 5 foot V as well.

As stated---I can drive three 137" sleds in from the front or rear.

I can easily drive two and back two 137" sleds with room for gear.

I recently purchased a Legend 19 x 7.5 plus an extra 6" tall fits 2 renegades in the winter and my SXS and a atv in summer. I have had just about every different configuration of trailer and this is the best of all worlds. Most universal, best weather protection, security, storage and great for all your gear, parts, etc. Front ramp door is a must. I hated backing out sleds in a hybrid trailer I owned. Good luck.

Sorry not sure why photos turned sideways

 

That's a really nice Legend. I almost bought the same one but like the NEO door latch better (just easier to use).
