Julian not sure if this will help you to calculate out what you can or cant expect your trailer to weigh once you have it all put back together or not but I can give you some details in regards to the Scamp 16' Standard side bath that appears on the Real World Weight Thread
twice as trailer # 33 & #37 as its my own trailer.
Its a pretty standard Scamp 16' in regards to options - or at least based on the ones I have seen over the years at meets. Is a 1992 model so it does have the rat fur and foil bubble insulation. It does not have AC or an oven. It does have an awning
, small fridge
stove & furnace, fresh and grey water tanks and a hot water tank. A wet bathroom with toilet and attached black tank. One propane tank and a group 27 battery
on the tongue.
In regards to its loaded status at the time of both the recorded weigh ins it had *no* water in any tanks. At the time it was weighed on both occasions it was fully loaded for 3 to 4 weeks of camping. Everything in it from the portable bq, chairs, a small portable stove for outside use, food, clothing (although only two small box 13" x 13" square of clothing), lanterns, dishes and pots and pans etc. and a mid sized tote box full of hoses, chocks, electrical
On number 37 - when it was heavier on the axle
but lighter on the tongue than when weighed at #33 I was also carrying a portable cooler in the trailer. I had on that trip made a point of adjusting where items where stowed in the trailer to try and keep the tongue weight at or below the 200lb tongue weight limit spec on my Subaru Outback - something I havent done again or would not do again due to how unstable the trailer felt with that light
of tongue weight % to the axle
weight when traveling at speeds over 55 mph. A weight distribution hitch to correct the issue is not an item recommend for use by the tugs manufacture.
After the #37 weigh in I know I needed to increase the % of tongue weight to the axle
weight, so I tried to reduce the axle weight to achieve that. Due to there not being much of anything in the way of needed items to remove and most of the items I was carrying where purchased with the intent of getting the lightest products possible the only thing of weight I could remove was the portable cooler. It now travels in the back seat of the car - as I only carry one passenger if any. I also due to having to go over the tugs specs on the tongue to achieve a solid tow dont like to carry much other than golf clubs in the rear of the car.
The weights shown on #33 are now pretty well the numbers I see when it has been weighed again. I do tend to weight it a couple of times a year just to be sure it hasnt managed to gain weight & will give it a good clean up at of all the little stuff that can start to add up if it is suffering from a minor weight gain problem ;-) I have a rule that if I add something new to the trailer something else has to go. For example when I added a fairly light
small flat screen TV to the trailer my kitchen had to loose one large pot and a couple of extra coffee mugs to accommodate the added weight. So yup I am pretty careful about what I load into the trailer & the relevant weights. ;-)
I know that if I was to be only going on a 2-3 night trip I could shed some items out of the trailer but I dont think it would be much more than 100lbs worth (which would bring it down to the lightest weight 16' Scamp on the list) but I know on longer trips I would miss having most of those items greatly.
Hope that back ground on at least one of the 16' on the list helps you in some way.
