2010 Volvo VNL780 truck and 2016 trailer

in my truck alone i have $ 103 000 invested in truck purchase , parts and service , in my 2016 53 feet Great Dane dry van trailer $ 32 000 , the truck has orig. 904 000 miles now but still runs very well. The reason i m looking to trade is because it maybe be the only way i can get some value back in exchange , i have all the receipts for truck and trailer purchase, parts and service.
