Yes, there's so many different ways of putting a 'roof' over your head that you need to decide what's required/important (usually governed by the Mrs!)
Different styles could be summarised as follows (although each category has numerous versions to accomplish the same thing)
1. Tent (maybe you've got one?)
2. Camper trailer (tent on wheels)
3. Windup Camper (caravan with canvas walls and sleeping areas)
Some Pros/cons of each would be as below. Everyone would have different views of this. Prices range wildly in each category... but I'll guess some indicitive ones, using a low 2nd hand price to a top-of-the-range new price)
- Don't need to tow anything (if your other holidaying requirements can be kept minimal)
- Need to put it up although tents these days are much simpler than of days gone by.
- easy to store at home
- need to consider bedding (blow up lilo's don't take up much room but some don't like sleeping on them)
- Lots of storage for junk
- Can have inbuilt kitchen facilities/fridges/12V power
- lot dearer than a tent
- can be suitable for serious off-road destinations
- two major classes of these, hard floor and soft floor.
- Still sleeping under canvas
- easier to tow than a full sized van
- permanent inside table to sit at
- still got mod cons (fridge/sink/microwave)
- can have HWS/AC and even shower and toilet, but not many would option these.
- simple to setup
- need to be able to store it at home/etc. can fit under carports that full vans won't
- Most storage space
- most expensive to tow (fuel)
- hardest to tow (wind/weight/vision although you can get pop-tops and things like the Ecotourer that have lower travelling profiles)
- most mod cons (can have shower/dunny/AC/HWS)
- Needs to be pretty big to get more than one permanently made-up bed inside (can have bunks too)
- minimal set up required
- need somewhere to store it at home
In fact, as mentioned, there can be so many options it can be bewildering. The type of holidays you take and where combined with just how much luxury/convienence you desire probably governs what you should be looking at. Money doesn't grow on trees so that's always an overriding factor.
A 1yo might require some kind of cot to sleep in and those travel ones aren't exactly small. This will be a issue whether your in a tent or camper-trailer. In a wind-up camper you could turn one of the bed-ends into a cot quite easy. If you had a caravan without 2nd permanent bed setup, putting the young one down at night could be a pain unless you can put them to sleep in your bed and move them to the temp bed later at night when you want to retire.
Usually our biggest problem is the amount of clothes and stuff my wife takes, mostly for our sons. Not sure when it last snowed at the beach, but we'd have clothes suitable!
You don't mention if you've already got a tent, but on a recent week away I noticed a lot of people toteing huge amounts of junk with them. Seemed a common method to accomplish this was to tow a box trailer loaded to the brim with everything (including the tent) that wasn't tied down at home.
In summary... it all very complicated!
