Looking at getting a better trailor. Right now I just Have the
L3300 fel and loaded tires. May get a larger farm tractor(75hp?) soon. Have 3/4 dodge diesel to pull with. Truck has a goose neck hitch. Never had a GN but I understand these are much better than the bumper pulls I'm used to. I'm thinking at least 20' 14k trailor.
Found a 24k tilt bed deck over(It's way over kill but its cheap), I know these are good for track machines but are they any good for rubber tire tractors?
As for as dove tails the inside fender deck are alot cheaper than a deck over, is the 7' width ok for most equipment or should I stick with a deck over for 8'?
Well, you've just about got 'em all covered!
For years, I used a "bumper pull" equipment trailer. (21K 3-axle) IMHO, stay away from tri-axles. BIGTIME tire wear issues unless you NEVER make any turns

Bumper pulls get the job done, and generally cost less than a gooseneck. BUT...Give me a gooseneck any day of the week. Less porpoising at speed. Better weight distribution on tow vehicle. (with a well designed hitch)
I personally like "deck-over" trailers. Low profile w/ fenders restrict side loading (i.e. forklift/lumber) Lower profile makes for SLIGHTLY easier loading, but not so much I'd sacrifice the full width deck. Both of my goosenecks are full legal width of 8'-6". At times I wish they were only 8', but trailers are like barns and garages. No matter how big they are, you can always use one that's bigger.
Mine are 20', w/5' dovetail. The dovetail raises to level with the deck, giving a 25' flat. GREAT for hay haulin'! 2 fold down ramps also.
I picked 14,000gvwr models.
I prefer a longer deck than absolutely required. That gives you more flexability to move load forward or rearward to balance weight as needed. Too big is better than too small in just about every case.
I owned a tilt bed trailer years ago. No real negatives other than the fact they usually require a much heavier chassis/deck construction, lowering allowable cargo weight. The angle of the deck can be steep while in loading position on some tiltbeds. Watch that when planning for a rubber tired tractor. Trailer decks can be slick at times.
A 75hp tractor will generally be heavy enough that you'll want AT LEAST a 12,000 gvwr trailer. (remember, the weight of the TRAILER [and weight scaled on tow vehicle] needs to be deducted from gross weight to compute cargo capacity)
That's my experience with trailering. Your results may vary.
