I have a 2000 SR85 4runner V6 4WD. It has 169000 mi. and going strong. I have never towed with it but would like to get a small tent trailer. The trailer dry unit weight is 2214 and I figure 800 lbs will cover cargo, water, etc. Everything I read tells me this will work, but I don't want to get into it and find I need a V8. Can you help?
