Short Version
My DH thinks I am being very unreasonable but AIBU to want to sell MY things to fund a cheap old caravan which I will use ON MY OWN with our children, so they can have a holiday ?
Long Version
My DH works very hard to support our family, whilst I'm currently a SAHM to our 4 DC's. DH is happy with this arrangement and I will be returning to work in a couple of years time, when our youngest is at school.
Our budget does not cover luxuries like proper holidays and so we usually have a few day trips each year. However last year my MIL invited us to stay in a static caravan for a week with the DC's and we had a ball. Really enjoyed the beach, the children's playgrounds on site and the onsite swimming pool.
I have been trying to convince my DH to buy a tourer caravan to enable us to have cheap self catering holidays but he claims to hate tourer caravans though he has never had a holiday in one. He had previously claimed to hate static caravans too, but really enjoyed last years holiday in one...all I wanted him to do was have a go before making a decision on how he feels about it, but he is stubborn (like me) and he remain unconvinced.
I decided that I will sell anything I have of value which I paid for pre-children...my laptop, my mobile phone, my collection of baby slings (bought with maternity money for first child), mobile cashbacks etc and buy a cheap caravan.
Looking to spend (if I manage to raise this much money) £400 or less on a 4/5/6 berth one with a minimum of two double beds, to pile my small children on. If anyone has one they are getting rid of in the North West PM me. 
I don't expect my DH to come away in this caravan, I will go on my own with the children. No, it won't be a relaxing holiday for me but the idea is to give the children a nice time and I'm on my own with all the children every school holiday anyway. I do hope DH might try it one day but I am buying it with no expectations of him ever setting foot in it, as he hates caravans. 
DH is still against the idea of me even self funding a caravan and when I mention my caravan fund (barely started), he is very negative and is trying to put me off the idea...telling me I can't put the caravan on our drive...I could put the caravan on our double drive but this would mean I would have to park my car on the road which I am willing to do but he says no.
I aim to buy a couple of food tins every food shop through out the year, to put in the caravan, that is what we did as children. Had a tourer holiday where we ate tinned food for a week with fruit ! Then the money I would of spent on a food shop the week of the holiday, can cover site fees on a basic caravan park...we'll have so much fun.
Caravan insurance will be around a £5 a week/month (can't remember which) and this I will take out of the child benefit for our youngest which we have just started receiving and isn't currently in our budget IYSWIM, as it is a benefit for our children.
My father has already agreed IF i get a caravan he will be willing to tow it nearby for me (within a couple of hours drive). So I don't need to get a tow bar, nor worry about towing the caravan. I'm sure my father will help me set it up for me on site :)
DH's parents live permanently in a caravan travelling around Europe and England and I'm sure I could pitch up next to them for a few nights. They don't see enough of the grandchildren and I'm sure would love for me to do this. Likewise my own parents are retired and have a tourer and would love to spend a few days at the seaside with their grandchildren.
AIBU to buy a caravan ?
