We ordered our 16' this spring and it arrived just in time for summer camping. We basically went with almost everything because we didn't want to add things later. Here's a quick run down of my post purchase thoughts...
Standard vs. Deluxe
Deluxe adds weight and the cabinetry is harder to keep clean. Sure it looks good, but it's a camper not the kitchen in your McMansion. The fiberglass cleans up easy...and it does and will get wet and dirty because you are camping!
We haven't used either yet, but its nice to know its there. We'll get to it eventually but for now we're happy with using campground amenities.
This is a must. Do not order yours without it! Perfect for sites where you don't have 120v for the a/c. Perfect for when you are cooking to keep the smoke/steam out.
We've used it already and are glad it is there. You have to pay a premium for sites with 120v hookups but in the summer it's good to know there is a way to escape
the heat and get a good night's sleep.
We went with the big one. It's overkill for weekend camping. I always stock food first and fill the rest with adult beverages...I haven't run out of adult beverages yet
We got one for fall
camping but it probably won't get much use. It's probably something I would have passed on in favor of having that space for storage. We don't plan to camp in winter.
With our 16' it is useful. We use it. For a 13' I would follow the recommendations above and get a mosquito tent or something instead.
Skipped this one, we don't go camping so we can watch TV. If that's our plan we'll stay home! If you plan to full-time or something I could see this option getting more use.
Dual Gas Tanks
Not sure we needed this, especially since we don't plan to do winter camping. I just figured i wouldn't ever have to worry about running out. The fact is, we use very little gas on our trips so i'm not sure we'll use up a single tank all summer long let alone two.
this is an absolute must. It works great and allows you to keep the door open on nice days.
Get them all. They shouldn't be optional, they should all be standard features.
2" receiver for bike rack
We skipped this option after reading about complaints with sway. It can be added later fairly cheap.
We used it a few times but could probably use the storage space instead
Hot water heater
Unless you plan to use the shower you probably don't need this. I turned ours on to make sure it worked but haven't bothered with it on our camping trips since we don't use the shower.
12v water pump
We use it but don't leave it on. When city water isn't available it comes in handy.
This is a must. I can't imagine having carpet. My wife is constantly sweeping the dirt out.
12v and 120v jacks
We had them install all. We've used everything except the one on the outside.
front porch light
Used it a few times to find the right key and open the door but not a must have.
As others mentioned, we told scamp to omit the curtains on all windows
except the door. We bought parts from IKEA and installed our own. Check out my forum thread for details.
