"He was worth around £ 400,000 when he bought it, but as much of what he has, he has collapsed in value"
It is said that the star of the broken reality has a debt of £ 250,000 and was narrowly avoided bankrupt last week.
But she was snubbed by a horse dealer who offered her £ 90,000 for the custom vehicle that cost several more times.
One source said: "The horse box is probably worth around £ 150,000 now, but they know you're desperate, you can not blame them for trying to get a good deal with that.
"He was worth around £ 400,000 when he bought it, but as a large part of what he owns he has plummeted in value."

Katie, owner of three horses, bought the transporter several years ago. She made a series of adaptations and painted it bright pink.
Katie, 40, is currently unable to drive after being shut out of the roads in February for six months for speeding.
Last week he was given 12 weeks to come up with a plan to pay off his debts or face bankruptcy. The star of busty reality was estimated at £ 45 million in 2012, but he has squandered his fortune and is now in a mountain of debt.
The former girl has won £ 6.2m in reality shows, £ 3.5m in an Asda lingerie collection and sold more than three million copies of her books. But two costly divorces and the collapse of his company made a big hole in his finances.

She also ruined a fortune in plastic surgery, vacations and a £ 1m farm. The model was forced to put on sale its extensive mansion of West Sussex, whereas the recent images showed that the last two months had sold the 2 million dollars.
According to reports, the cottage, which is said to be £ 100,000 in arrears on the mortgage, cost him £ 10,000 per month to maintain, which he now can not pay.
A deal would mean that she could keep it and other assets. In an additional hit, Katie could face an unlimited fine for driving while prohibited.
She was seen driving from Gatwick Airport last month. Katie did not respond to our request for a comment.
